The Surin Islands lie close to the Myanmar border in the northern Andaman Sea and form a national marine park of five islands, granite coves and some of the clearest water in Thailand. They are further from Phuket than the Similans, which means fewer visitors and a quieter feel, and the coral in the shallow bays is a draw for snorkellers. The two-day trip from Phuket turns a long journey into an experience by including an overnight stay, so you wake up near the reefs instead of racing back. The itinerary typically includes several snorkelling stops, time on the beach, a visit to a community of the Moken sea nomads and a night in basic accommodation on the island or on a boat. For travellers who like wilderness over luxury, it is one of the most rewarding trips in the region, and it pairs well with a Similan Islands day for the full northern Andaman experience.
How it works
The trip begins with a pickup early in the morning and a drive north to the pier near Khuraburi, followed by a boat ride of around an hour or more to the islands. After arrival you snorkel at one or two sites, have lunch and spend time on the beach.
Accommodation is simple, often tents or small bungalows run by the national park, with shared facilities, and you eat meals provided by the operator. On the second day you snorkel again, visit another bay and head back to the mainland in the afternoon. Park fees are normally paid in cash.
What to expect
The reefs in the Surin Islands are in good condition, with hard and soft corals, giant clams and many species of reef fish. Turtles and reef sharks appear occasionally. The Moken, a traditional sea people, have a village on Koh Surin Tai, and respectful visits can give you some insight into their culture, with photography permitted only with consent.
The nights are quiet, with a sky full of stars because there is no light pollution. Conditions are basic, so expect limited electricity, warm showers that may not be hot and cold drinks that run out. The park is open only in the dry season, from mid-October to mid-May.
Making the most of it
Pack light in a soft bag, with a head torch, insect repellent, a reusable water bottle, reef-safe sunscreen and a rash vest. Bring cash for fees and souvenirs, as there are no banks. Seasickness tablets help on the crossing, which can be bumpy. Ask the operator about sleeping arrangements and what is provided. Respect the park rules: do not touch the corals, do not collect shells and take rubbish with you.
Because mobile signal is limited, tell family where you will be. Booking early is wise in high season, since accommodation is limited. If you want a shorter option, consider a day trip to the Similans, but the Surin overnight gives more time in the water and a deeper sense of remoteness.
Consider how you will use the long journey. The drive north is a chance to see the countryside of Phang Nga, with palm groves, mangroves and small towns, and many travellers bring a book or download music for the road. Keep valuables to a minimum, and leave anything fragile at your Phuket hotel before departure.
