How much does Koh Tao cost per day in 2026?

The budget figure starts with a 350-baht ($10) dorm bed in Sairee, and several dive-school hostels along Sairee Beach still price beds close to that. Food is the second bucket. A pad krapao with a fried egg from the Thai stalls on the back road behind Mae Haad pier runs 70 to 90 baht ($2-3), and the same plate on the Sairee beachfront costs 160 to 200 baht; the extra pays for the sunset view. Plan on 400 baht ($12) for three meals if you eat where the dive instructors eat. Refilled water and a 7-Eleven iced coffee add 60 baht, and two large Chang bottles add about 120 baht ($3.60). On the west coast, walking replaces the taxi trucks: Sairee to Mae Haad is about 25 minutes on the concrete road, and this week it is sticky and overcast at 28°C with 73% humidity. Keep 150 baht for laundry at 40 to 50 baht per kilo, a SIM top-up and the odd small fee. That brings the day to about 1,080 baht.

Midrange is where most Koh Tao trip reports end up. A fan bungalow or basic air-con room in Sairee or Chalok Baan Kao costs about 1,200 baht ($36), a scooter adds 250 baht ($7.40) a day plus 50 baht of fuel, and by the second hill the two-stroke exhaust is unmistakable. Food rises to about 800 baht ($24) once you add a sit-down dinner at Su Chili in Sairee, where a green curry and a cold, tart mango shake likely come to around 300 baht. Two beers at a Sairee beach bar cost about 200 baht, with fire-show drums thumping on the sand behind you. The last 100 baht covers one viewpoint fee, putting the day at roughly 2,600 baht. Any day with a round-island longtail snorkel trip, at 700 to 850 baht ($21-25), goes over that number.

Most people take the ferry to Koh Tao for the diving, and that shapes every number above. The Open Water price in the summary usually includes three or four nights in a shop-owned dorm or a discounted bungalow, so ask about the room deal before you start comparing course prices. Shops that come in 2,000 baht under the big Sairee schools often drop the free bed, and that wipes out the saving. Fun dives currently cost about 1,000 to 1,200 baht ($30-36) each and get cheaper in packs of 10. At 18 metres, the cheapest instructor on the island is the wrong one to pick. Skip the 300 to 400 baht cocktail buckets on Sairee on dive nights too: most shops won't take you out with a hangover at 6am.

Free things on Koh Tao exist, but most come with a catch. Sairee Beach costs nothing, though by noon its coarse sand is too hot to walk on barefoot. Ao Tanote on the east coast is free for swimming and snorkelling, but the taxi truck from Mae Haad tends to cost around 300 baht per person unless you fill it. Freedom Beach, south of Chalok Baan Kao, charges roughly 50 to 100 baht because you cross resort land to reach it. John-Suwan Mountain Viewpoint charges about 100 baht for a 20-minute scramble over hot granite, with views over Chalok bay and Shark Bay. Ao Leuk has a gate on its access road, so snorkellers either pay or arrive by longtail. Koh Nang Yuan, the sandbar trio off the northwest coast, charges a landing fee that has run about 100 baht in recent years, and it also bans plastic bottles, so staff take the 7-Eleven water you brought at the jetty.
