Koh Lanta boat tours and snorkelling

4 Islands and Emerald Cave: beaches with an adventure

For a mix of island scenery, beach time and a memorable cave visit, start with the 4 Islands trip. The route is built around Koh Ngai, Koh Mook, Koh Kradan and Koh Chuak, with the day’s stops shaped by access and sea conditions.

Emerald Cave on Koh Mook is the highlight for many visitors: a passage through the rock leads to a hidden beach enclosed by cliffs. Reaching it involves being in the water and passing through a dark tunnel, so mention children or anyone less confident in the water when you enquire.

Choose this direction if your group wants variety rather than a day focused entirely on snorkelling.

Koh Rok and Koh Haa: make snorkelling the main event

If getting in the water is the reason for your boat day, Koh Rok and Koh Haa belong on your shortlist. These offshore islands offer reef scenery and an escape from Koh Lanta’s beach road.

Koh Rok brings island beaches and snorkelling; Koh Haa adds dramatic rocky islands and underwater scenery. Speedboat options make these further destinations practical for a day trip. Tell us whether you prefer more time in the water or a balance of swimming and beach stops.

Phi Phi, Maya Bay and limestone lagoons

For the island views you have been saving for your holiday, look towards Phi Phi. Ask us about Phi Phi trips visiting Maya Bay, or routes featuring Bamboo Island and Pileh Lagoon. We will help you compare the options for your date.

Maya Bay is a beach visit rather than a swimming stop. Pileh Lagoon offers a different setting, surrounded by limestone cliffs, while Bamboo Island is known for its sandy shores. Your chosen itinerary will show which places belong in the same day.

Choose how you want to spend the day

The destination comes first; then we help match the boat and booking style to your group.

• Longtail: a traditional boat and an unhurried feel for routes suited to it.
• Speedboat: useful for covering more distance to offshore islands.
• Join tour: share the boat and follow an organised itinerary with other travellers.
• Private trip: book a boat for your own group and discuss a more personal plan.

Turn your shortlist into a booking

Send your preferred trip, date, number of adults and children, and where you are staying. If you are undecided, tell us what you enjoy and we can start there.

We will put the available options into a quote with the itinerary, boat type, departure arrangements, price and included items, including how transport, food, snorkel equipment and park fees are handled. You can review the booking and weather terms before deciding.

Some island sites close seasonally, and weather affects routes. Sharing an alternative date gives you more room to find the boat day you want. Need a separate ride to the pier? Arrange a Koh Lanta taxi in the same conversation.
