Similan Islands Snorkeling Khao Lak: Speed Catamaran & Sailing Rock
What if you could snorkel three islands and climb a rock that overlooks them all in one morning?
You're picked up from your hotel and taken by speed catamaran to three snorkeling sites across the Similan Islands, including Island No.5 with its coral and fish, Christmas Point, and Sailing Rock on Island No.8, where you climb to a panoramic viewpoint. Lunch is a Thai buffet served on board, and all gear, transfers, and insurance are included in the price. The whole day takes about seven to eight hours, and the tour runs October through May when the national park is open.
Is this one for you?Book this if you're in Khao Lak between October and May and want the main Similan Islands snorkeling stops without arranging your own boat, permits, or timing — the speed catamaran and fixed itinerary fit multiple islands and a viewpoint climb into one morning, and hotel transfers mean you don't navigate the port yourself.
What’s included
Your day includes hotel pickup and drop-off, round-trip transport by speed catamaran, snorkeling equipment (mask, snorkel, fins, and life jacket), three snorkeling stops across the Similan Islands, a climb to the Sailing Rock viewpoint on Island No.8, a Thai traditional buffet lunch served on board, fresh fruit, an English-speaking guide, and full travel accident insurance coverage.

The Similan Islands snorkeling tour from Khao Lak runs October through May, and it's built around the speed catamaran that gets you out to the archipelago fast enough to hit multiple spots before lunch. You start at Island No.5, where the water is clear enough that you see the fish before you enter it — colorful corals, schools moving together, the kind of visibility that makes you forget you're holding your breath. The guide is English-speaking and stays with the group, pointing out what you're looking at underwater without the usual resort-tour feel.
After Island No.5, there's a second snorkeling stop, and then the boat takes you to Sailing Rock on Island No.8 — the actual landmark of the Similan Islands, a towering formation that rises from 25 meters below. You can climb it. The viewpoint at the top gives you the whole archipelago laid out, and most people spend twenty minutes up there taking photos or just sitting with the view. Then you come back down, swim if you want, and the group moves to lunch — a Thai buffet served on the boat, fresh fruit after. The whole day is maybe seven to eight hours from pickup to drop-off, and the speed catamaran means less time bouncing on the water than you'd get on a slower boat.
The tour includes snorkeling gear (mask, snorkel, fins, life jacket), round-trip hotel transfers, travel accident insurance, and a guide who speaks English. One thing to know: Similan National Park requires your passport details after you book so they can process your entry ticket in advance. It's not a hassle, but it's a step you can't skip. The park only opens those eight months, so if you're in Khao Lak between October and May and want to see the islands without arranging your own boat and permits, this is the straightforward way to do it.
