Koh Lanta Diving, Small Groups, Great Personal Service
Our dive shop @ Lanta Castaway Beach Resort is located at the south end of Long Beach, and we are Koh Lanta's original boutique scuba diving centre.
We operate two custom designed diving speedboats to Koh Lanta's best dive sites.
Our fast boats can reach Koh Lanta's dive sites in as little as 30 minutes, saving you hours of travel time on larger, slower dive boats, especially if you plan more than 1 day diving.
Short Journey Times
Dive trips to Koh Haa and Koh Bida / Phi depart Koh Lanta at 9 am, normally returning around 1:30 - 2.00 pm each day.
Dive trips to Koh Rok depart Koh Lanta at 8 am, again returning around 2 pm.
When diving Hin Daeng & Hin Muang from Koh Lanta, or Shark Point & Anemone Reef, our speed boats depart just after 8 am, returning around 2 - 2:15 pm.
All our dive trips are 2-tank dives, with a maximum of 10 divers on each of our boats, plus our dive staff. Divers are split into 3 or 4 smaller groups, each with their own dive guide or professional instructor.
E-mail us email@example.com for any Lanta diving questions, or booking requests.
Diving Koh Lanta
Koh Lanta is not just one island, it's an archipelago of 52 islands, many of which are part of the Mu Koh Lanta Marine National Park, home to some of the best scuba diving in Thailand.
When people say they love Koh Lanta's diving, they are usually referring to the 6 limestone islands of the Koh Haa archipelago, the magical coral-fringed Koh Rok islands, and the deeper pinnacles of Hin Daeng & Hin Muang located at the far south of the Mu Koh Lanta Marine National Park.
Lanta's breath-taking scuba diving and snorkeling sites are between 30 minutes and 75 minutes by speed boat from our dive shop @ Lanta Castaway Beach Resort, located at the south end of Long Beach.
More information on our dive sites.
Diving Koh Phi Phi
In addition to wonderful diving around Koh Lanta, we also have quick and easy access by speedboat to the best dive sites around Koh Phi Phi from Koh Lanta.
Diving the Bida Islands, Koh Phi Phi Leh, diving Hin Klai, and the HTMS Kledkaeo wreck from Koh Lanta is just a quick 35 - 40 minute speedboat trip.
Whilst not far from Koh Lanta, the dive sites around the Bida islands and Koh Phi Phi are quite different from those in the Lanta Marine Park. The underwater topography, coral species and growth forms, and abundance of other marine species vary noticeably between the two.
The Shark Point & Anemone Reef dive sites are slightly further away from Koh Lanta, sitting between Phi Phi and Phuket, and are best visited in February, March or April.

Scuba Skills Refresh
We understand that those who have not dived for a while might feel a little anxious about getting back into the water.
Even for those who are more confident divers, if you've not been diving for a while, you'll enjoy improved buoyancy, air consumption, and confidence in the water after a light scuba skills refresher on Koh Lanta with our experienced dive staff.
We conduct the scuba skills refresher at the beginning of the first dive to help ease you back into the water.
We'll also include a quick theory review and extended dive briefing to make everything as smooth as possible and ensure that you have the best possible dives around Koh Lanta.
For those who have not dived in a long time, or who are feeling less confident in the water, we can provide a full scuba skills review in confined water the day before diving from the boat.
For Enriched Air certified divers, we have 32% Nitrox available at 250 Baht per tank during the high season here on Koh Lanta.
If you're not already a Nitrox certified diver, it's really easy to add the Enriched Air Nitrox course here on Lanta to a 2 tank dive trip while you're diving with us.
Please remember that our dive guides will always dive an 'air' profile, even if some of our divers are using Nitrox.
If you're already Open Water Certified (or equivalent SSI, BSAC, NAUI, etc.) and plan to dive around Koh Lanta for at least 3 days then you can also boost your scuba skills and knowledge to the next level by taking the Advanced Open Water Diver course on Koh Lanta at the same time.
Include 5 Adventure Dives over 3 days of diving, diving deeper, learning how to navigate unknown dive sites, improving your buoyancy, and expanding your knowledge of the amazing underwater world.
Private Speedboat Charter
For the perfect dive or snorkel trip, you can also privately charter a speed boat on Koh Lanta to some of the most beautiful islands, beaches, and coral reefs in the Andaman Sea.

Already here on Koh Lanta?
If you're already here on the island then dive trip bookings can be made in person at our dive shop @ Lanta Castaway Beach Resort (south end of Long Beach, about 100m from the 7-Eleven).
Dive bookings can be made between 10 am and 5 pm and are confirmed on receipt of a deposit.
We need to see all divers at our office at the time of booking to complete the paperwork, check dive certifications, check equipment sizes, receive the deposit, etc.
Why do we need to see you the day before a trip?
All dive equipment is packed the evening before a trip and loaded to our boats early the next morning before our office opens. This means that check-in with us on the morning of a dive trip is not possible.
We also like to meet all our guests the day before diving as this helps us to plan the dive groups and staff, answer any last minute questions, and hopefully avoid any last-minute surprises on the morning of a trip.
All of this helps us to be better organised and provide a higher level of service.
Please bear this in mind when planning your journey to Koh Lanta.
