Snorkelling Trips from Phuket: The Stops and What Gear Is Included

Almost every island trip from Phuket calls itself a snorkelling trip, and most of them are not. A boat that anchors for twenty minutes off a beach so that people can put their faces in the water is selling a swim stop. What decides whether you see anything is the reef the boat stops at, how long it stays, and whether the water there is three metres deep or thirty.

Our inventory of Phuket listings held 563 offers on 17 September 2026, of which 142 are sold under snorkelling, from €19.59 with a median of €79.53. That spread of four times the price is not a quality gap. It is the distance to the reef.

The stops, and what each one is

Those last two lines are the whole argument. The reefs everybody means when they say “snorkelling in Thailand” are in Mu Ko Similan and Mu Ko Surin national parks, off Phang Nga rather than Phuket, and they are closed for the monsoon every year from mid-May to mid-October. For 2026 the parks shut on 15 May and reopen on 15 October. If you are reading this in September, no operator can take you there, whatever the listing says. The Similan Islands snorkelling trip by speedboat is a 12-hour day from €88.80 with 4.5 stars from 1,805 reviews, and it is a genuinely different class of reef – but only between mid-October and mid-May. The Surin Islands day trip, 8 hours from €112.30, follows the same calendar.

Inside the closed season the honest answer is Racha Yai. It sits outside any national park, about 45 minutes out, and the sheltered bays on its east side hold visibility that Coral Island loses by ten in the morning. The Racha Island snorkelling or diving day is listed from €54.08.

What “equipment included” covers – and what it does not

This is the line in the listing that people skim. Three things are worth separating.

Life jackets are not an inclusion, they are the law – and since 2025 that covers the water, not just the boat. Thai regulations require operators to carry jackets for every passenger and to brief people on them before the boat leaves, so an operator treating that as a selling point is telling you nothing. A ministerial regulation in force since 22 April 2025, issued under the Marine and Coastal Resources Management Act and running for five years, goes further: a vest is compulsory for snorkelling anywhere in Thailand, and the only exemption is a recognised freediving certificate you can produce on request. A jacket holds you upright, which is the opposite of the position you want for looking down at a reef – but on a Phuket day boat that is not the crew being careful, and asking to leave it off is asking them to break the rule. The same regulation makes the guide explain fin control before you get in, and keeps snorkellers at least two metres clear above the coral.

Mask and snorkel are usually included. Fins very often are not. The listings are inconsistent about this, and the difference matters more than it sounds: without fins you cannot hold position against even a gentle current, and on a deep-water stop you spend the whole twenty minutes swimming back towards the boat. Some operators rent them on board, some do not carry them at all. The booking page’s inclusion list is the only place this is answered.

A mask that leaks ruins the stop. Boat masks are shared, stretched and often the wrong size, especially for children and for anyone with a beard. If you snorkel more than once on the trip, a cheap mask from any Phuket pharmacy or beach shop pays for itself on the first stop.

Nobody supplies wetsuits here, and you do not need one – the Andaman Sea sits near 29 °C most of the year. Rash vests are your own problem, and on a boat with no shade they are the difference between a good afternoon and a burnt back.

The fee that is not gear but lands on the same bill

Snorkelling stops inside a national park carry an entrance fee, collected in cash at the pier and usually not in the listing price. Hat Noppharat Thara–Mu Ko Phi Phi National Park covers Phi Phi and Bamboo Island; out at the islands it is 400 THB for foreign adults and 200 THB for foreign children, and the 200 and 100 some operators quote is the mainland rate for the same park near Krabi. Ao Phang Nga is 300 THB and 150 THB, Mu Ko Similan and Mu Ko Surin 500 THB and 250 THB.

Coral Island, Racha Yai, Maiton and the Khai islands are outside the parks and carry no such collection. For a family of four that is a real difference on a day when the headline prices are within a few euros of each other – the same arithmetic that decides the choice in Coral and Racha or Phi Phi.

When the cheap snorkel trip is the right one anyway

If the point is that the children get in the water somewhere calm and shallow, the Khai islands trip from €19.98 does that better than a reef three hours away, and the 15-minute crossing is the reason – see Phuket island hopping with children. Nobody there is looking at coral. They are looking at fish in waist-deep water, and that is a perfectly good day.

What does not work is booking a Phi Phi day trip for the snorkelling. Those stops are short, deep and crowded, the boat is on a schedule built around Maya Bay, and swimming in the cove itself is not permitted. Go for the scenery, which is its own decision, and treat the snorkelling as a bonus.

Before you pay, three questions answer most of it: which named stops, how many minutes at each, and are fins included. All three are on the booking page – the rest of the snorkelling listings and the broader island trips are easier to read once you know what you are looking for.
