Chiang Mai from €66 Gibbons, trekking and Mae Kampong small-group tour
A day in the mountains around the village of Mae Kampong: a forest trek with a chance of seeing wild gibbons, and local food along the way.

Start with what you want to do. For each activity: where in Thailand it is at its best, when to go, how hard it is and three real tours to book.
Thailand rewards travellers who plan around an activity rather than a list of towns. The best climbing is in one small corner of Krabi; the cheapest dive courses are on one small island; the finest trekking is in the hills of three northern provinces. This page sorts the country by what you do, and links each activity to the destination guides where you can do it — tap a destination to go straight to its tours page.

Day and overnight treks through forest, rice terraces and hill villages in the north; humid rainforest trails to waterfalls in Khao Sok; guided wildlife walks in Khao Yai. Go with a local guide — trails are rarely marked.

The most satisfying trips mix two or three of these. Trek and raft in the north, then fly south to climb and paddle. Learn to dive on Koh Tao, then kayak Ang Thong. Our itineraries are built around combinations like these, and when to go shows which activities suit which month.
Whatever you choose, check that your travel insurance covers it: scuba diving, climbing, rafting and riding a motorbike are commonly excluded unless you add them.
Climbing courses, dive trips, small-group treks and marine-park boats run with limited places and fill up from December to February and in July and August. Compare what is bookable online and reserve in a couple of taps.
Among active travellers: learning to dive on Koh Tao, sport climbing at Railay and trekking around Chiang Mai. Sea kayaking in Phang Nga Bay is close behind.
Plenty. Rafting is at its best, waterfalls are full, and sheltered kayaking, climbing on shaded walls, muay thai, cycling and ziplining all continue. For beaches and diving from June to September, choose the Gulf islands.
Many are: island-hopping, easy kayaking, elephant sanctuaries, cycling tours and short treks all work for families. Diving courses have minimum ages (usually 10), and ziplines have height and weight limits.
Not automatically. Read the policy wording for diving depth limits, climbing, rafting grades and motorbikes, and add cover where needed. Reputable operators will ask you to sign a liability form.
