Thailand
Koh Samui is the Gulf of Thailand's easy island: coconut-fringed beaches, a green mountain interior, golden temples and a ring road that puts almost everything within an hour.
This guide books it properly, starting with the great boat days, Ang Thong National Marine Park with its 42 limestone islands, the Koh Tao and Nang Yuan sandbar, Pig Island and a sunset junk boat to Koh Phangan, then adds the island's own highlights: the Big Buddha, an ethical elephant sanctuary visit, a 4WD jungle safari, a treetop zipline, a Thai cooking class and a Muay Thai fight night. Then it matches you to the right hotel, from a private-pool villa in a hidden bay to beachfront resorts on Bophut, Choeng Mon and Chaweng, because on Samui the beach you choose decides your evenings.
Ang Thong National Marine Park Day Trip
A day among the 42 limestone islands that float north-west of Samui: kayak between karst walls, climb to the viewpoint on Koh Wua Talap, swim and snorkel off pale beaches and look down on the emerald lagoon on Koh Mae Koh. The big-boat tour is the best-value way in, with lunch on board and a full day outdoors.
Koh Tao and Koh Nang Yuan Snorkeling Day Trip
A speedboat run north to Koh Tao and the three-island sandbar of Koh Nang Yuan, with snorkel stops over lively reefs and time on one of the Gulf's best-known beaches. The short crossing makes it an easy, high-reward day.
Big Buddha and Samui Island Highlights Tour
The seated Big Buddha on its own islet is Samui's landmark, and a half-day highlights tour ties it to temples, viewpoints and a waterfall in one air-conditioned loop. It is the easiest way to see the island's cultural side on a first visit or a rainy day.
Pig Island and Koh Tan Snorkeling Tour
A short speedboat hop from Samui's north-east coast to Koh Madsum, the island where pigs come down to the beach, and to the coral around Koh Tan. Easy, cheerful and good for families, with snorkelling and a chance to spot pink dolphins.
Hand-picked: every experience here has strong traveler reviews and a verified booking link.

A full day under sail on a Chinese-style junk boat, cruising to the quieter bays of Koh Phangan for swimming and snorkelling, then drifting back at sunset. A relaxed, social alternative to the speedboat circuit.

A half-day visit to a home sanctuary where retired working elephants are watched and cared for rather than ridden. Observation-based, unhurried and a far better choice than any riding show.
Hop on an open-sided 4WD jeep for a bumpy day through Samui's green interior: waterfalls, mountain viewpoints, temples, a local lunch and plenty of laughs. A reliable crowd-pleaser, and a good wet-season plan.
Fly through the rainforest canopy on a string of ziplines, cross a tree bridge and take in sea views, with a cafe-bar in the treetops. Thrilling, but gentle enough for confident beginners.
Start at a local market, then cook a multi-course Thai meal under a guide's eye and eat what you make. A hands-on half day that shows how southern Thai food works, with transfers included.
A live evening of Thailand's national sport: bouts under the lights, ringside drama and the pre-fight Wai Khru ritual to music. Loud, local and a memorable change from beach evenings.
