Snorkeling and Diving Around Koh Lipe

Published 1 October 2026 · By the Visit-Thailand editorial team · Editor: Terje Moy

Koh Lipe is one of the best bases in Thailand for snorkeling, because the reefs of Tarutao National Park start a few minutes from its beaches. You can snorkel from the sand at Sunrise Beach, take a longtail boat to the islands of Koh Adang and Koh Rawi, or dive deeper sites with one of the island's dive shops. The best months are the dry season, roughly December to April.

The island lies inside the area of Tarutao National Park, a marine park of 51 islands set up in 1974 and one of the original ASEAN Heritage Parks. That status brings rules, a park fee and seasonal closures of some reefs, and this page explains all three. It is a guide to the water around Lipe; for the island itself, see our Koh Lipe guide.

Snorkeling from the beach at Sunrise Beach

The easiest reef is the one you can walk to. At the southern end of Sunrise Beach, coral starts close to shore, and on a calm morning you will see reef fish, anemones and corals in water no deeper than your waist. You need nothing more than a mask, a snorkel and fins, which you can rent from shops along the beach and on Walking Street.

The catch is the depth. At low tide the reef flat is barely covered, and that is when people stand up on coral, cut their feet or step on something venomous. Go at mid to high tide and float over the reef. Our article on stonefish on Koh Lipe tells what happened when one of our group was stung near this spot and lists the first aid that matters. Our comparison of Koh Lipe's beaches covers the other two beaches, which are better for swimming than for snorkeling.

Longtail snorkel trips to Koh Adang, Koh Rawi and the islets

The best snorkeling is a short boat ride away. Longtail boats, the local wooden boats steered with a long-shafted engine, leave from Pattaya Beach and Sunrise Beach for half-day and full-day trips. You can join a shared tour sold at the kiosks on Walking Street, or hire a boat and driver for your group and choose the stops. Either way, you visit three or four sites and usually stop on a beach for lunch.

The islands you will hear named are all within the national park:

• Koh Adang, the large, forested island directly north of Lipe, with reefs along its shores and a park camping area at Laem Son.
• Koh Rawi, west of Adang, with long beaches and reefs on its sheltered sides.
• Koh Yang and Koh Hin Ngam, small islets near Koh Rawi. Koh Hin Ngam is known for its beach of smooth, dark stones. Leave them where they are.
• Koh Dong, Koh Hin Son and the Chabang channel, which longer trips and dive boats visit for their soft corals.

On a shared trip, ask before you pay whether the park fee is included, how many sites you will visit and what time you will be back. On a private longtail, agree the price, the route and the return time with the driver before you leave, and pay in cash at the end. Bring water, sun protection and a shirt for the boat, because there is no shade on most longtails.

Diving: what to expect and how to choose a shop

Several dive shops operate on Koh Lipe, mostly on Walking Street and at Pattaya Beach and Sunrise Beach. They run day trips to sites around Koh Adang and Koh Rawi and to deeper pinnacles further out, and most offer beginner courses and "try dives" for people who have never dived. The sites are a mix of granite boulders, hard coral slopes and pinnacles with soft corals; how far out a shop goes depends on the weather and the group's experience.

We do not recommend individual dive shops, and you should be wary of anyone who calls a shop "the safest" without saying why. Instead, check these points before you book:

• The shop is affiliated with a recognized training agency such as PADI or SSI and can show you the instructor's credentials.
• Group sizes are small, especially for courses (ask how many students per instructor).
• The equipment is in good condition, and the briefing covers the park rules: no touching, no standing on coral, no collecting.
• The price states clearly whether the national park fee and any extra diving fee are included.
• Your travel insurance covers scuba diving to the depth you plan to dive. Many basic policies do not; our guide to travel insurance for Thailand explains what to look for.

Remember how remote you are. Koh Lipe has only a small clinic, and anyone with a serious injury or a diving-related illness has to be taken to the mainland by speedboat, a trip that took our stonefish victim about five hours in total to reach hospital. If you want to do a full course, a busier diving center such as Koh Tao may suit you better; our guide to learning to dive on Koh Tao covers that option.

The park fee and the park rules

Tarutao is a category 2 park under the national park fee system, which means 200 baht for a foreign adult and 100 baht for a child (as of October 2026). Thai nationals pay less. Children are defined as aged 3 to 14, or up to 140 cm tall. The fee is normally collected in cash; boat and dive operators may include it in their price or ask you to show your ticket.

The rules in Thai marine parks are much the same everywhere. The list that the park authorities publish for Maya Bay in Krabi is typical: do not collect coral, shells or any sea creature; do not bring sunscreen with chemicals that harm coral; do not bring foam containers; do not litter; do not feed the fish; do not fly a drone without permission; and boats must not drop anchor on the reef. Following them around Koh Lipe is simple:

• Never stand on coral or hold on to it, even when you are tired. Swim to sand or back to the boat.
• Keep your fins up and away from the reef, and stay horizontal in the water.
• Do not feed fish, even with the bread some boat crews hand out.
• Use a mineral sunscreen, or better, a long-sleeved rash guard.
• Take all rubbish back to Lipe, including cigarette ends.

Seasonal closures in the national park

Parts of Tarutao National Park close every year during the southwest monsoon, both to let the reefs recover and because the sea is unsafe for small boats. In its 2024 notice, the park closed Koh Lek, Koh Bissi, Koh Talang and the north and east sides of Koh Adang from 1 June to 31 July; Koh Yang, the Chabang channel, Koh Rawi, Koh Dong, Koh Hin Son, the west side of Koh Adang and several smaller islets from 1 August to 30 September; and all park bungalows and campsites from 16 May to 30 September.

The dates are set by a new notice each year, so check the current one with the park before you plan a trip around a particular reef. The village on Koh Lipe itself stays open year-round. Our guide to the best time to visit Koh Lipe combines the closures with the ferry seasons.

When visibility is best

The calmest and clearest water usually comes in the dry months, from about December to April. The Thai Meteorological Department's long-term averages for Satun, the nearest mainland station, show only about 40 mm of rain in each of January and February, against more than 330 mm in each of September and October. Rain brings runoff and plankton, and the wind from the west stirs up the sea, so visibility drops and boat trips are cancelled more often during the monsoon.

Water temperature is warm all year, so a thin rash guard or shorty wetsuit is enough. In the wetter months, check the sea on the morning you go: a calm day in October can still be good, and a windy day in March can be poor. Jellyfish are more common in the rainy season; our guide to jellyfish in Thailand covers prevention and first aid, and dangerous animals in Thailand covers sea snakes, lionfish and sea urchins.

If you are combining Lipe with other dive areas on the Andaman coast, the Similan Islands further north and the Trang islands are the obvious companions.

Frequently asked questions

Is the snorkeling good on Koh Lipe?

Yes. You can snorkel from the beach at the southern end of Sunrise Beach, and longtail trips reach healthier reefs around Koh Adang, Koh Rawi and the small islets within minutes. Conditions are best in the dry season, from about December to April.

How much is the national park fee on Koh Lipe?

Tarutao National Park charges foreign adults 200 baht and children aged 3 to 14 100 baht, the category 2 rate (October 2026). Pay in cash and keep the ticket, because it may be needed for day trips to the surrounding islands.

Can beginners dive at Koh Lipe?

Yes. Dive shops on the island run introductory dives and entry-level courses. Choose a shop affiliated with a recognized agency, ask about group sizes, and check that your travel insurance covers diving, because serious cases must be taken to the mainland by boat.

Is snorkeling around Koh Lipe possible in the rainy season?

Often, yes, but with limits. Some reefs inside the national park close in the monsoon months, boat trips are cancelled on rough days, and visibility is usually lower. The shore reef at Sunrise Beach remains reachable on calm days.
