About this tour
When Mia from our team ran this tour, we headed out on a speedboat from Koh Lanta to Koh Rok — an uninhabited island only reachable by water, packed with marine life most mainland tourists never see. The eight-hour outing splits time between snorkelling with a guide, padding about white-sand beaches, and tucking into a Thai lunch aboard the boat. The crew from Tin Adventure Sea Tour keeps groups small enough to actually chat with, and hotel pickups mean you're not sorting transport. It's the kind of day that rewards the effort of getting to Koh Lanta in the first place.
Highlights
- Speedboat-only access means fewer tourists than standard island hops
- Guided snorkelling boosts your odds of spotting reef fish and larger marine residents
- White-sand beaches nearly empty of other tour groups
- Fresh Thai lunch with seasonal fruit prepared aboard
- Hotel collection and drop-off removes logistical friction
- Small-group dynamic lets guides know your names and preferences
- Peaceful boat crew who chat about local marine conservation
What to expect
You'll leave your accommodation early — transport picks you up and takes you to the speedboat dock. Once aboard, the ride to Koh Rok takes a fair while, but the water's gorgeous and the crew hands you life jackets and snorkelling gear without fuss. First stop: into the water with your guide. The marine life is genuinely abundant; reef walls, schooling fish, the occasional ray. You'll get a solid hour or two of snorkelling, then the boat heads to a quieter beach patch where you can float around or rest on the sand. By midday, lunch appears — a simple buffet of Thai curry, rice, and fruit. Afternoons are a mix of more snorkelling or beach time, depending on conditions and group energy. The return to Koh Lanta takes its own time, but you're usually back by late afternoon, tired and salted.
The pacing feels unhurried. Mia found the boat crew genuinely engaged rather than mechanically running a script. Water clarity can vary with season, and wave conditions do affect comfort, but the guide adjusts accordingly. The uninhabited status means zero beach infrastructure — toilets are aboard the boat, so plan accordingly.

Good to know
Koh Rok is genuinely harder to reach than its neighbours, so you'll share the reef with far fewer snorkellers than you'd find at Koh Phi Phi or Koh Lanta's doorstep. The guide-led snorkelling is a real plus if you're keen to learn what you're looking at. Hotel pickups save time, and the small-group cap keeps things sociable. The crew's friendly and lunch hits the spot after hours in saltwater.
Minimum group size is 10 — if numbers don't hit that, they'll reschedule or refund you, but it's worth confirming a few days before. The national park entry fee (400 THB per adult) is on top of your tour cost. The boat ride's lengthy; if you're prone to motion sickness, bring patches. Not suitable if you're pregnant, have heart conditions, high blood pressure, or spinal issues. Early departure (likely 6–7am) suits early risers but not hangovers. Bring a rash guard for sun protection and reef scrapes.
