TL;DR: Mu Ko Surin National Park runs a short season, roughly 15 October to 15 May, and is shut the rest of the year for monsoon safety, so check it’s actually open before you plan around it. A day trip from Khao Lak costs about ฿3,200-3,700 (~US$97-112) for adults including the ฿500 (~US$15) national park fee, with hotel pickup around 6:20-7:40am, a speedboat from Khuraburi Pier around 9am, and return to Khao Lak by early evening. Multi-day trips with bungalow or tent accommodation on the islands run from about ฿6,700 (~US$203) for 2 days/1 night up to ฿8,200-10,900 (~US$248-330) for 3 days/2 nights or a snorkelling liveaboard, and get you calmer water once the day-trip boats have left. The reefs at Chong Khad, Mai Ngam and Ao Sapharot are some of the healthiest in the Andaman, and every trip includes a stop at the Moken sea gypsy village on Ko Surin Tai. All prices ฿33 = US$1 (July 2026).
If you’ve searched “Surin Islands from Khao Lak,” you’re probably weighing the same question everyone does: a long day trip, or paying more for a night or two actually on the islands. Mu Ko Surin National Park sits far enough offshore, and closes for long enough each year, that it doesn’t get the same relentless boat traffic as the Similans or Krabi’s island circuit, and that’s exactly why the reefs and the water here still look the way postcards promise. This guide covers the season, the day-trip logistics from Khao Lak, what a liveaboard or multi-day trip adds, the national park fee, and the Moken village that’s part of every itinerary. Every price and date below is checked against 2026 operator listings and national park sources, linked at the end.
When are the Surin Islands open?
The park operates roughly 15 October to 15 May and is fully closed May to October for the monsoon. Outside that window the crossing from Khuraburi Pier is too rough for tour boats, and the park itself shuts to protect the reefs and the Moken community from storm damage. The safest, calmest stretch sits from November through April, with the shoulder weeks either side of that (mid-October and early-to-mid May) more weather-dependent, since operators can open a little later or close a little earlier than the official dates if the sea isn’t cooperating. If you’re planning a trip near either edge of the season, confirm directly with a Khao Lak operator before booking flights around it.
Day trip from Khao Lak: what it actually involves
A day trip is a genuinely full day, typically 9-11 hours door to door, not a quick half-day excursion. Hotel pickup in Khao Lak runs early, usually 6:20-7:40am depending on where you’re staying, followed by a road transfer of roughly 1.5-2 hours up to Khuraburi Pier, since the pier sits about 85-90km north of Khao Lak. The speedboat itself departs around 9-9:30am and takes roughly 1 to 1.5 hours to reach the islands, with the return crossing leaving the islands around 4:45-5pm. Once you add the road transfer back to your hotel, most travellers are back by early evening, having spent the middle of the day snorkelling, eating lunch at the park restaurant, and visiting the Moken village.
Surin Islands day trip and multi-day options compared
| Option | Duration | Price (adult) | Price (child 4-11) | What you get |
|---|---|---|---|---|
| Day trip | ~9-11 hrs door to door | ฿3,200-3,700 (~US$97-112) | ฿2,300-2,600 (~US$70-79) | Speedboat crossing, 2-3 snorkelling stops, lunch, Moken village, national park fee usually included |
| 2 days / 1 night | Overnight on the islands | ~฿6,700 (~US$203) | ~฿4,700 (~US$142) | Everything in the day trip plus a night in a tent or bungalow and a quieter afternoon/evening on site |
| 3 days / 2 nights | Overnight on the islands | ~฿8,200 (~US$248) | ~฿5,600 (~US$170) | More snorkelling sessions across two full days, better odds of calmer, less-crowded bays |
| Snorkelling liveaboard | 3 days / 2 nights on a boat | ~฿10,900 (~US$330) | Ask operator | Sleep aboard rather than on the island, around 8 snorkelling sites, buffet-style meals |
National park fee (฿500 / ~US$15 adult, ฿250-300 / ~US$8-9 child) is included in most packaged prices above; confirm with your operator if booking independently. Compiled from Surin Islands operator listings; see Sources.
What does the national park fee cover?
The Mu Ko Surin National Park entrance fee is ฿500 (~US$15) per adult and roughly ฿250-300 (~US$8-9) per child, charged separately from transport if you’re arranging the boat yourself. Most packaged day trips and multi-day tours quote an all-inclusive price that already folds the park fee in, so you shouldn’t be asked to pay it again on arrival if you’ve booked a package. If you’re travelling independently to Khuraburi Pier and buying your own boat ticket, budget for the park fee as a distinct line item paid at the park entrance.
Is the snorkelling really that good?
Yes, this is consistently rated among the best reef snorkelling in the Andaman Sea, and the short season is part of the reason why. Chong Khad Bay is the main arrival point, with clear, calm water suited to most swimmers. Mai Ngam Bay is shallower and more sheltered, a good choice if you’re less confident in open water. Ao Sapharot (Pineapple Bay) and Jaak Bay both have healthier coral cover and better visibility than the more heavily trafficked Similan sites, largely because Surin sees far fewer daily boats and is shut entirely for five months a year. Which two or three bays you actually visit depends on conditions on the day, decided by your guide.
The Moken sea gypsy village
Every itinerary, day trip or multi-day, includes a stop at the Moken village on Ko Surin Tai. The Moken are a traditionally seafaring, semi-nomadic people who lost boats and belongings in the 2004 tsunami and resettled permanently on the island afterward; around 300 people live there today across roughly 78 houses. You can walk through the village and buy handmade souvenirs, so bring small baht notes since change isn’t always available. Dress modestly and ask before taking photos of residents. This is a lived-in community rather than a cultural show put on for tourists, and it’s worth treating the visit that way.
Day trip vs liveaboard: which should you book?
A day trip covers the highlights in one long day for the lowest cost; a multi-day trip or liveaboard buys you calmer water and more time in it. For most travellers slotting Surin into a wider Khao Lak trip, the day trip at ฿3,200-3,700 (~US$97-112) delivers the main snorkelling bays, the Moken village, and the whole experience without committing extra nights. If you’ve got the time and budget, staying over, whether in a park bungalow, a tent, or a dedicated liveaboard at ฿6,700-10,900 (~US$203-330), means diving in once the day-trip boats have headed back to Khuraburi in the afternoon, plus extra snorkelling sessions the single-day itinerary can’t fit in.
Honest downsides
- The season is short and weather-dependent. Roughly seven months a year the park is simply closed, and the shoulder weeks in October and May can shift without much notice if the sea turns.
- It’s a long day for a day trip. Between the road transfer to Khuraburi and the boat crossing each way, you’re looking at 9-11 hours total, most of it in transit rather than in the water.
- The crossing can be rough. Even within the open season, a 1-1.5 hour speedboat ride in swell isn’t for everyone; if you’re prone to seasickness, medicate beforehand.
- Multi-day accommodation is basic. Tents and bungalows on the islands are simple, seasonal, and limited in number, not a resort experience, so set expectations accordingly.
Bottom line
Surin Islands rewards the extra effort it takes to get there, quieter reefs, a real Moken village visit, and snorkelling that holds up against anywhere else in the Andaman, precisely because the short season and remote pier keep the crowds down. Book the day trip if you want the highlights on a tight schedule, or add a night or two if you can, since that’s where the quieter water and extra reef time actually pay off. Pair the trip with a look at things to do in Khao Lak, check the best time to visit Khao Lak since it lines up closely with Surin’s own season, and browse Khao Lak’s beaches for what to do on the days you’re not out on the water.
