Things to Do in Jackson Hole in August

PricesPeak Season

August in Jackson Hole is defined by a tension between the valley's finest hiking weather and the peak of western wildfire smoke season. Daytime temperatures reach the mid-20s Celsius (upper 70s Fahrenheit), nights dip to single digits, and Grand Teton National Park's 300-plus km of trails are entirely snow-free. But smoke from fire complexes burning across Idaho, Montana, and California has blanketed Teton County for days at a stretch in recent Augusts, turning the Cathedral Group into a gray outline on the horizon. It happened in 2018 and again in 2022. You might get two spotless weeks of blue sky, or you might not see the summit of the Grand at all.

The month still delivers when skies cooperate. The Snake River runs at levels friendly for scenic floats through the park, and the Grand Teton Music Festival fills Walk Festival Hall in Teton Village with orchestral performances through mid-August. The town of Jackson, population roughly 11,000 year-round, feels like it triples. Town Square's elk-antler arches become a slow-moving photo line by 10 a.m. most mornings, the scent of coffee and sunscreen drifting through the boardwalk.

The trade-off is clear. You get Jackson Hole at its most accessible, warmest, and most alive. You also get it at its most expensive, with lodging rates that rival the peak ski weeks in February. If smoke stays away, the Teton Range in August is as good as mountain scenery gets in the Lower 48. If it drifts in, you still have the National Museum of Wildlife Art (founded 1987, set into the hillside above the National Elk Refuge), a twice-weekly rodeo with dust and cheering under the evening sky, and restaurants that merit a trip on their own.

Why visit in August

All high-elevation trails in Grand Teton National Park are snow-free by August, including Paintbrush Divide at 3,200 m (10,500 ft), which typically holds snowpack into early July.
The valley's flagship classical music series closes its summer season with gala finale concerts in mid-August, drawing audiences from across the Mountain West.
Low humidity keeps afternoon warmth genuinely comfortable for hiking, cycling, and float trips, without the sticky quality of East Coast or Gulf Coast summers.
Berry season draws bears, moose, and elk into visible feeding areas along the Moose-Wilson Road corridor and through Cascade Canyon, making this one of the year's strongest months for wildlife viewing.

Worth knowing

Wildfire smoke from fires across the western U.S. can descend on the valley for days, dropping visibility to under 2 km and making strenuous hiking inadvisable for anyone with respiratory sensitivity.
This is one of the two priciest windows in the valley's calendar, and last-minute lodging availability within the park or near the ski base area is nearly nonexistent.
Traffic on Teton Park Road and the Moose-Wilson Road backs up badly on weekends, with trailhead parking lots at the most popular access points often full before 8 a.m.
Afternoon thunderstorms build over the Teton Range most days, bringing dangerous lightning above treeline between roughly 1 and 4 p.m.

Crowds peak

Pack Layering is essential when mornings start in the single-digit Celsius range and afternoons warm considerably. Bring a lightweight insulating mid-layer for early starts, high-SPF sunscreen for intense UV at elevation, and a packable rain shell for the near-daily afternoon storm cycle.

August brings warm, dry-leaning days and cool nights to the valley floor at 1,900 m (6,237 ft) elevation. Morning temperatures settle near 9°C (48°F), climbing to around 25.1°C (77°F) by early afternoon. Afternoon thunderstorms develop over the Teton Range on most days, typically between 1 p.m. and 4 p.m., though they tend to be brief and localized. Rainfall averages 49 mm across about 7 rainy days for the month. The air feels dry at 58% average humidity, though a passing storm can soak a ridgeline trail in minutes. Late August occasionally previews autumn with overnight lows that dip closer to 5°C (41°F) at higher elevations.

Seasonal caution

Wildfire smoke from fires across the western U.S. can blanket the Teton Valley for days in August, reducing visibility and pushing air quality to levels unsafe for prolonged outdoor exertion. Monitor AirNow.gov daily and keep flexible backup plans.
Afternoon thunderstorms above treeline produce dangerous lightning with limited warning. Begin high-elevation hikes before 7 a.m. and plan to be below treeline by early afternoon.

Best things to do in August

Hike the Teton Crest Trail

hiking

A 60 km (37 mi) multi-day traverse through the heart of the Teton Range, passing alpine meadows, high divides, and glacial lakes. The trail connects Teton Village to Paintbrush Canyon via some of the most exposed and scenic terrain in the northern Rockies.

All sections are snow-free by August, including Paintbrush Divide and Hurricane Pass, which hold snowpack through June and often into July. August offers the widest reliable window to complete the route without ice-axe travel.

Booking tipBackcountry camping permits through recreation.gov open January 5 and competitive zones fill within hours. Apply early and build a flexible itinerary.

Scenic float trip on the Snake River

water

A 16 km (10 mi) guided float through Grand Teton National Park, drifting past cottonwood-lined banks on water cold enough to sting if you trail a hand. Bald eagles, osprey, and moose are common sightings from the raft, with the Teton Range filling the western horizon.

Water levels have mellowed from June's snowmelt peak, making the current gentle and the float comfortable. Warm afternoons and golden August light make this the most photogenic window for the trip.

Booking tipBook morning departures at least 2 weeks ahead. Early floats before 9 a.m. see more wildlife and calmer water.

Guided ascent of the Grand Teton

climbing

A 2-day guided climb to the highest summit in the Teton Range via the Owen-Spalding route or the Exum Ridge, requiring an overnight at the Lower Saddle camp. Prior mountaineering experience is expected by most guide services.

The standard routes are in prime condition through August, with stable rock and minimal residual ice on the upper pitches. August also offers the longest daylight window for summit-day starts.

Booking tipGuide services fill months ahead for August dates. Book by March at the latest and confirm your fitness meets the prerequisites.

Dawn wildlife drive on the Moose-Wilson Road

wildlife

A slow, early-morning drive along the 12 km (7.5 mi) Moose-Wilson Road between Moose and the Laurance S. Rockefeller Preserve, scanning willow thickets and berry-laden meadows for bears, moose, and the occasional fox or coyote. The air along this road at dawn carries a sharp pine-and-sage scent that softens as the sun climbs above the Gros Ventre Range.

Pre-autumn hyperphagia drives grizzly and black bears into visible foraging areas along this corridor in August. Moose with late-summer calves frequent the willow flats at dawn.

Booking tipNo booking needed, but enter from the Moose (south) end before 7 a.m. on weekends. The road closes to new entries when parking fills.

Paddle Jenny Lake at dawn

water

Launch a kayak or canoe into the calm, glass-clear water of Jenny Lake before the afternoon wind picks up. The lake sits at the foot of Cascade Canyon with the Cathedral Group reflected in the surface on still mornings.

Lake surface temperatures reach their annual warmest in August, around 10-12°C (50-54°F), and morning calm before afternoon thermals provides the year's best flatwater conditions for paddling.

Booking tipRental kayaks and canoes are available near the Jenny Lake Visitor Center. Arrive before 8 a.m. to secure one on weekends.

Attend the Jackson Hole Rodeo

culture

A traditional Western rodeo held at the Teton County Fairgrounds in Jackson, featuring bronc riding, barrel racing, calf roping, and bull riding. The atmosphere is rowdy, family-friendly, and about as far from a polished tourist experience as the valley gets.

The summer rodeo series runs Wednesday and Saturday evenings through Labor Day in early September. August performances benefit from long, warm evenings with sunset light over Snow King Mountain.

Booking tipTickets are available at the gate, but popular Saturday performances can sell out by mid-afternoon. Arrive by 6 p.m. for good seating.

Cycle the Jackson to Jenny Lake pathway

cycling

A paved multi-use pathway runs roughly 30 km (18.5 mi) from the town of Jackson through Grand Teton National Park, largely separated from vehicle traffic. The route passes through sagebrush flats with Teton views that open wider the further north you ride.

August's dry, mild conditions make the full ride comfortable without the cold headwinds of June or the occasional heat spikes of late July. The entire pathway is clear and the daylight window is generous.

Booking tipSeveral outfitters in Jackson rent road and hybrid bikes. E-bike rentals are available but check park regulations on where motorized bikes are permitted.

Hike to Taggart Lake and Bradley Lake

hiking

A moderate 9.5 km (5.9 mi) loop trail starting from the Taggart Lake Trailhead, passing two glacial lakes tucked beneath the Tetons with views of Avalanche Canyon. The trail gains about 260 m (853 ft) and suits fit beginners.

The loop is entirely snow-free and the wildflower meadows along the approach still carry late-summer blooms in early August. Afternoon shade from the canyon walls keeps temperatures comfortable even on warm days.

Booking tipArrive before 8 a.m. to park at the trailhead. After that, the lot overflows to the road shoulder.

What to eat in August

In season: fruit

Wild huckleberries
Tiny, intensely sweet-tart berries that ripen across the Bridger-Teton National Forest and surrounding slopes from late July through August. They cannot be farmed commercially, which makes them a genuine seasonal find. You will see them in pies, jams, pancake syrups, and cocktails across the valley's restaurants.

On menus now

Wyoming range bison
Summer-fattened bison from Wyoming ranches appears on most serious menus in the valley. The meat is leaner than beef with a slightly sweeter, grassier depth that reflects high-altitude pasture. Expect it as ribeye cuts, burgers, and slow-smoked preparations.
Pan-seared local trout
Trout preparations peak on August menus throughout the valley, often served with brown butter, fresh herbs, and seasonal vegetables. The flesh is firm and clean-flavored, a product of cold mountain-fed water.

What to drink

Huckleberry lemonade
The signature warm-weather drink of the Teton region, blending fresh huckleberry syrup into cold-pressed lemonade. Nearly every cafe in downtown Jackson pours a version from late July through September, each one a slightly different shade of purple.

Regular events in August

Jackson Hole Rodeo

Wednesday and Saturday evening rodeo performances at the Teton County Fairgrounds featuring bronc riding, barrel racing, calf roping, and bull riding. A local summer tradition rooted in the 1890s.

Every Wednesday and Saturday evening, late May through Labor Day (early September)

Jackson Hole People's MarketFree

A Saturday morning farmers market and artisan fair on the Town Square area featuring local produce, huckleberry products, Wyoming-made goods, and live music.

Saturdays, approximately 9 a.m. to noon, through early October

Grand Teton National Park ranger-led programsFree

Free daily programs including guided nature walks, evening campfire talks at Colter Bay and Jenny Lake campgrounds, and stargazing events. Topics rotate weekly and cover geology, wildlife, and Teton history.

Daily through August, schedules posted at park visitor centers

Best places this August

Schwabacher Landing
viewpoint
A riverside access point on the Snake River about 6 km south of Moose Junction, famous for dawn reflection photography when the Tetons mirror in still beaver ponds. August mornings tend to be calm before thermals build, making this the best season for the shot. Moose frequent the willows along the bank.
Moose
Laurance S. Rockefeller Preserve
nature preserve
A 4.5 km (2.8 mi) interpretive trail network on the southern shore of Phelps Lake, designed for quiet contemplation rather than peak-bagging. The preserve caps visitor numbers through limited parking, making it one of the few places in the park that feels uncrowded even in August.
Moose
Chapel of the Transfiguration
historic site
A small log chapel built in 1925 near the Moose entrance to Grand Teton National Park. Its altar window frames the Teton Range, and the surrounding meadows carry late-summer wildflowers into early August. Episcopal services run on Sunday mornings through summer.
Moose
George Washington Memorial Park
park
The main green space in downtown Jackson, shaded by mature cottonwoods and used for community events throughout summer. A good place to rest between restaurant stops and watch the August foot traffic pass through.
Downtown Jackson
Jackson National Fish Hatchery
nature
A working federal fish hatchery founded in 1950 at the base of the Gros Ventre Range, raising native Snake River cutthroat trout. The outdoor raceways and interpretive displays are open to visitors year-round, and the site doubles as a quiet picnic area away from the park's main crowds.
Kelly
Snow King Mountain
mountain
Jackson's town hill, rising directly above the south end of downtown. Summer operations include a scenic chairlift, an alpine slide, and hiking trails that offer views down the valley toward the Gros Ventre Wilderness. The summit trail is a steep but short climb from town.
Downtown Jackson
Murie Residence at the Murie Ranch
historic site
The historic home of conservationists Olaus and Mardy Murie on the edge of Grand Teton National Park. The ranch played a central role in the campaign that led to the 1964 Wilderness Act and is now a National Historic Landmark with interpretive tours available in summer.

Wide-brimmed sun hatExposed ridgeline and alpine meadow hikes above treeline offer zero natural shade. A hat with a full brim protects ears and neck through hours of direct sun. Shop
Sturdy hiking boots with ankle supportRocky, root-laced Teton trails are harder on feet than groomed paths in lower-elevation parks. Trail runners work on valley-floor paths, but anything above benefits from stiffer soles. Shop
Refillable water bottle with filter or purification tabletsMountain streams are abundant in Grand Teton backcountry, but untreated water carries Giardia risk. A filter saves carrying extra weight on long day hikes. Shop
Binoculars (8x42 or similar)Wildlife viewing along the Snake River corridor and from Teton Park Road turnouts rewards magnification. An 8x42 pair is light enough to carry daily and powerful enough to identify a grizzly at 400 m. Shop

Insider tips

Start Cascade Canyon and Paintbrush Canyon hikes before 7 a.m. to secure parking at trailheads. By 8:30 on weekends, the park begins turning cars away from the busiest lots.
Wilson, about 10 km west of Jackson on WY-22, has restaurants that draw fewer tourists but serve food at the same caliber as downtown. Locals eat there to sidestep the August foot traffic on the Square.
If smoke rolls into the valley, check conditions at the top of the Jackson Hole Mountain Resort aerial tram. Inversions can trap haze below 2,500 m while the air clears above. A tram ride to Rendezvous Mountain sometimes puts you above the smoke layer entirely.
The one-lane unpaved section of Moose-Wilson Road between the Rockefeller Preserve and the northern exit closes to new entries when its limited parking fills, often by 9 a.m. on weekends. Enter from the south (Moose) end early.
The Saturday morning market draws locals who shop around 8 a.m. and clear out before the visitor wave arrives after 10. Huckleberry products sell out first.

Avoid these mistakes

Too many visitors plan a full day above treeline without checking the afternoon forecast. Lightning kills more people in the Tetons than any other natural hazard, and storms develop with little warning after noon. Plan descents to finish by early afternoon.
Visitors who arrive at popular trailheads after 9 a.m. on a weekend will not find parking. The busiest access points in Grand Teton fill before most visitors finish breakfast. Consider the Jenny Lake shuttle boat as an alternative starting point.
The daily temperature swing catches many visitors off guard. Someone who starts a hike in a t-shirt at midday and gets caught at 3,000 m after a rainstorm risks hypothermia, even in August. Pack a warm layer for every outing above the valley floor.
Visitors who book accommodation only a few weeks ahead for August will find the valley sold out. The area fills months in advance, and last-minute openings typically mean staying 60 km or more from the park in towns like Driggs or Alpine.

Practical tips for August

Book lodging and guided activities 3-4 months ahead for August stays in Teton County. Grand Teton campgrounds at Signal Mountain and Gros Ventre fill early each morning on a first-come basis; Colter Bay and Lizard Creek are reservable through recreation.gov and should be booked by May. Bear spray is not sold at Jackson Hole Airport, so purchase it in town or at the Moose Village Store before entering the backcountry. Park entrance passes cover both Grand Teton and Yellowstone National Parks for 7 days. Cell coverage is spotty inside the park, especially in canyons, so download offline maps and trail data before leaving Jackson. The daily temperature range regularly exceeds 15°C, so carry layers on every outing regardless of how warm it feels at the trailhead. Restaurants in Jackson fill up for dinner between 6 and 8 p.m. throughout August, and reservations are worth making the day before, especially on weekends.

FAQ

Is August a good time to visit Jackson Hole?

August is one of the top three months for visiting, alongside July and September. Every trail is open, the weather is warm and generally dry, and the cultural calendar runs at full capacity. The trade-offs are peak-season pricing, heavy crowds at the most popular spots, and the unpredictable risk of wildfire smoke from fires burning elsewhere in the West. If you can stay flexible about your day-to-day plans in case smoke moves in, August rewards the trip.

What is the weather like in Jackson Hole in August?

August sits between Teton County's warm July peak and the cooler September transition. The daily swing between dawn lows and afternoon highs is wider than most summer visitors expect, so layering matters more than in flatter destinations. Humidity stays well below levels typical of the eastern U.S. Afternoon thunderstorms develop over the peaks most days but rarely last beyond an hour. The biggest variable is wildfire smoke from western fires, which can reduce visibility and air quality for days at a stretch.

Is Jackson Hole crowded in August?

Very. August is peak season for the valley, rivaling only the winter ski months for visitor volume. Expect heavy traffic on park roads, full parking at major trailheads by mid-morning, and restaurants that need reservations for dinner. Booking everything well ahead and starting each day early are the most effective ways to manage the crowds.

Do I need bear spray in Jackson Hole?

Bear spray is strongly recommended for any hiking beyond paved paths in Grand Teton National Park and the surrounding Bridger-Teton National Forest. Both grizzly and black bears are active throughout August as they feed intensively before autumn. You cannot fly with bear spray, so buy or rent a canister in Jackson when you arrive. Most outdoor shops in town carry them, and some offer end-of-trip buyback programs.

Can wildfire smoke ruin an August trip to Jackson Hole?

Smoke can diminish the experience but likely will not ruin it entirely. Smoke events in the Teton area typically last 3-7 days, and some Augusts see none at all. When haze does settle in, mountain views disappear and strenuous outdoor activity becomes less pleasant. Indoor alternatives like the wildlife art museum and the rodeo keep the trip worthwhile, and a 90-minute drive north to Yellowstone's geothermal features provides scenery that holds up well in hazy conditions. Flexible planning is your best defense.
