About this tour
When Charlie from our BugBitten team ran this speedboat tour from Koh Lanta, we hit four islands across seven-plus hours—Koh Chuek, Koh Mook (for the hidden Emerald Cave), Koh Kradan, and Koh Ngai. It's a proper island-hopping day that suits couples, families, and anyone after coral reefs and a breather on powder-white sand. The Trang Sea around here is genuinely clear, and the boat moves fast enough that you're not baking in one spot for too long. Mix of snorkelling, lunch on the beach, and a bit of time to just float.
Highlights
- Speedboat slices through crystal water, hits four islands in one day
- Emerald Cave on Koh Mook is a genuine hidden pocket worth the trip
- Snorkelling at Koh Chuek shows proper healthy coral and school fish
- Beachside lunch on Koh Kradan — sit in the sand, eat well
- Hotel transfers included, no mucking about with taxis
- Life jacket and snorkel gear provided; one less thing to hire
- Small-group feel — guides know who's who by lunchtime
What to expect
You'll meet at your hotel, get collected, and head to the speedboat dock. The boat itself is comfortable and quick — you're bouncing across the water but not white-knuckle rough. Each island stop lasts roughly an hour to 90 minutes, which is enough to snorkel, explore a cave, or just lie on the sand without it feeling rushed.
Koh Mook's Emerald Cave is the centrepiece: you paddle into a lagoon surrounded by limestone cliffs, and the water genuinely glows that pale turquoise. Koh Chuek offers the best coral and fish action. Koh Kradan is where lunch lands — buffet style, decent spread, and you eat with your toes in the sand. By the fourth island (Koh Ngai), you've either had enough snorkelling or you're keen for one more go. The crew keep an eye on everyone, and the guide gives you the gist of what you're looking at underwater. It's not a party boat, but it's relaxed enough that latecomers don't feel out of place.

Good to know
You cover serious ground in one day without hiring a private boat or stitching together four mini tours. The guide and safety gear are sorted, so you can just turn up. Hotel pickups save faff. The coral and cave are legitimately pretty, and the water is genuinely clean. Best for couples and families after a manageable adventure; no need to be ultra-fit.
The tour won't run unless there are at least 10 people, so book early and confirm a few days out. National park fees (200 baht adults, 100 baht kids) aren't included — you'll pay at entry. The speedboat can be noisy and the sea gets choppy on rough days. Not suitable if you're pregnant, have heart issues, or poor circulation; the operator takes this seriously. Early starts are standard for island tours, and you'll be in the sun most of the day, so sunscreen is non-negotiable. Lunch is buffet, so limited if you're fussy. Bring a dry bag if you care about your phone.
