Snorkeling in Thailand: Where, When and How to Pick a Good Tour

3 min readFrom the THAI TROPIC blog

First things first: which sea, right now

Snorkeling depends on the season. On the Andaman coast, home to Phuket, Krabi, Phi Phi and Koh Lipe, the sea is usually calmest in the winter months, roughly November to April. In the Gulf of Thailand, where Koh Tao and Samui sit, the season differs, and snorkeling is usually good from early in the year to mid-summer.

Seasons shift from year to year, so check the forecast before you book. Our east versus west coast guide explains the differences. Water visibility and waves shape the experience as much as the location.

How to choose a good tour

A small tour beats a mass one: fewer people in the water, more attention from the crew and less pressure on the reef. Ask how many people are in the group, whether a guide gets in the water and whether the gear is clean and fits.

A life vest matters even if you swim well, and a professional crew will remind you themselves. Use reef-friendly sunscreen, and note that some marine parks restrict certain types. Never touch the reef or feed the fish.

Koh Tao

Koh Tao is famous for diving, but it also suits snorkeling, with small bays and relatively calm water. Many travellers swim around Koh Nang Yuan and nearby bays, depending on season and sea. For diving, see our Koh Tao diving guide.

The island is small, so booking a local tour is easy. If you are looking for somewhere to stay on Koh Tao, here are some options.

The Andaman coast: Krabi, Phi Phi, Lipe and the Similans

From Krabi, boats head to the nearby islands, and Phi Phi is famous with plenty of boats, so go early. Koh Lipe is known for clear water, but the sea here too depends on the season. Read about Phi Phi and Koh Lipe.

The Similan Islands are a marine park that suits snorkeling, but it closes for the season, usually in summer, so check the dates. If you are looking for somewhere to stay around Krabi, here are some options.

Safety, gear and what to do next

Swim in a group, watch for currents and boats, and never snorkel alone. If the sea does not look safe, do not go in. Read the water safety guide before heading out.

Basic gear: a mask, a snorkel, a rash guard against the sun, and sometimes fins. You can rent, but a mask that fits makes for a better experience. Plan the trip with the budget calculator and pick a stay on the hotels page.
