How bad is altitude sickness in Cusco?

Nearly everyone feels it to some degree. Headache and fatigue are the most common symptoms, typically peaking on your first day in the city. Rest, coca tea, and staying hydrated help more than anything else. Most people feel close to normal within 48 hours of arrival.

Is Cusco safe for tourists?

Petty theft is the primary risk, particularly in crowded areas around the markets and on overnight buses. Bag snatching and pickpocketing happen, mostly after dark on quieter streets. Serious incidents involving visitors are rare. Take standard precautions and avoid walking alone late at night outside the Centro Histórico. The tourist police, Policía de Turismo, maintain an office on the Plaza de Armas for reports.

How many days should I spend in Cusco?

Three full days covers the historic center, San Blas, and the Inca sites on the hilltop circuit above the city. Add 2 more for a Sacred Valley loop through Ollantaytambo and Pisac, and at least 1 full day for Machu Picchu. A week is a comfortable total if you want to include a multi-day trek like the Salkantay or Lares route.

Can I use US dollars in Cusco?

Some hotels and tour agencies accept dollars, but you'll get a better deal paying in Peruvian soles. The current exchange rate is 1 USD to 3.3577 PEN. ATMs dispensing soles are easy to find in the Centro Histórico and Wanchaq, and major banks like BCP and Interbank have branches in both areas. Avoid the airport exchange desks, which tend to offer poor rates.

Do I need to book Machu Picchu tickets in advance?

Yes. Peru's Ministry of Culture caps daily visitors, and tickets sell out weeks ahead during peak season from June through August. Book through the official government portal to avoid third-party markups. Inca Trail permits sell out even faster, sometimes 3 to 6 months ahead for the peak window.

Is the tap water safe to drink in Cusco?

No. Stick to bottled or boiled water throughout your stay. Most hotels and hostels provide purified water or have filtration systems available for guests. Avoid ice in drinks at market stalls, and be cautious with raw salads at less established places. Bottled water is inexpensive and sold at tiendas and kiosks across the Centro Histórico and San Blas.

Cusco sits at 3,400 metres above sea level in a narrow valley of the Peruvian Andes, and the altitude announces itself before anything else: a tightness in the chest on the walk from the airport, a slowness climbing the first stone staircase. The city of roughly 428,000 was the capital of the Inca Empire, and the Spanish colonial centre that replaced it was built atop Inca foundations, a layering you can see along Hatunrumiyoc street, where the famous twelve-angled stone sits flush in a wall of fitted masonry that has survived five centuries of earthquakes. The Plaza de Armas anchors the old centre, flanked by the Cathedral and the Iglesia de la Compañía de Jesús, and from there the streets climb steeply into San Blas, the artisan quarter where workshops still produce carved wooden frames and ceramic work in styles that predate the colony. A first morning in Cusco usually begins slowly: coca tea at the hotel, a cautious walk to gauge how the body handles the thin air, and by afternoon most visitors find their rhythm along the pedestrianised stretches near Procuradores, locally called Gringo Alley with more resignation than affection. The neighbourhoods beyond the tourist core tell a different story: San Cristóbal on the hill above the plaza offers a view of terracotta rooftops spreading across the valley floor, and Santiago to the southwest is where the daily market economy runs without much regard for visitors at all. Cusco operates on Peru Time, five hours behind UTC, and the pace matches: shops open late, lunch stretches past two, and the light at this altitude turns gold an hour before sunset in a way that makes the sandstone glow. The city is not a base camp for Machu Picchu, though it gets treated as one; it is the destination.
