About this tour
When Em from our team ran this Similan Islands snorkel tour from Khao Lak with Sea Star Andaman, we spent eight-plus hours on modern speedboats visiting some of Thailand's sharpest reef and island spots. The outfit balances comfort with genuine diving action — guides pick sites based on that day's conditions and visibility, so you're not locked into a rigid route. You'll hit places like Stonehenge (dramatic rock formations rising from 25 metres down), Honeymoon Bay, and Christmas Point, where dolphins and sea turtles sometimes show. Lunch is proper Thai-style, and the crew sorts your snorkel kit and insurance. It's a solid operator doing what they do well.
Highlights
- Stonehenge reef site — towering submerged rocks create dramatic snorkel backdrop
- Flexible daily routing based on water conditions, not a fixed itinerary
- Honeymoon Bay exploration — beach time plus snorkelling in one stop
- Real chance of spotting dolphins and sea turtles, especially at Christmas Point
- Modern fleet with decent comfort for an eight-hour boat day
- Thai lunch and fresh fruit included; not just sad sandwiches
- Hotel transfers bundled in — no scrambling for separate transport
What to expect
The day kicks off with hotel pickup (early, so set an alarm), then a speedboat journey to the Similan Islands. Sea Star rotates between three main snorkel sites — Stonehenge with its jaw-dropping underwater rock formations, Honeymoon Bay where you'll get beach time and shallow snorkelling, and Christmas Point, a genuine wildlife hotspot. You'll be in and out of the water across the morning, with decent intervals to recover and grab water. The boat ride itself is bouncy but manageable; the crew hands you fins, mask, and a life jacket, so no gear stress. Around midday, lunch arrives — proper Thai curries and fresh pineapple, eaten onboard or on a beach. The afternoon squeezes in one or two more snorkel sessions before heading back to Khao Lak by late afternoon.
Our experience was straightforward: guides were attentive, visibility was solid (though this varies with season and weather), and the boat felt well-maintained. The pace suits mixed ability — you're not power-snorkelling all day, just steady dips with floats and support available. One thing to clock: the national park fee (400 baht per adult) isn't included, and they'll ask for your passport after booking so they can pre-register you. Not a hassle, just a heads-up.

Good to know
This is a proper mid-range snorkel tour that avoids penny-pinching on boats or guides. You're not crammed onto a groaning longtail with 50 people; the fleet size keeps groups manageable. Dolphins and turtles do appear — it's not guaranteed, but it happens. Insurance is included, which is rare on Thai boat tours and worth having. Suits swimmers of all levels, so confident snorkellers and nervous dippers alike fit in. Kids aged 4–11 get reduced tickets.
The eight-plus-hour day includes hotel pickup and drop-off time, so you're genuinely in the water for maybe five to six hours spread across multiple sessions — fine, but not an all-day reef marathon. The national park fee is a separate bill (400–200 baht depending on age), and you have to hand over your passport, which feels a bit admin-heavy. Early starts don't suit everyone. Conditions vary by season; if it's rough or cloudy, visibility can be disappointing. The tour isn't safe if you're pregnant, have heart issues, spinal injuries, or bone disease — read that list carefully. Heat and sun exposure are real, so sunscreen and hydration are essential, not optional.
Bring passport/ID, swimmers, towel, sunglasses, sunscreen, hat, camera. The kit (mask, fins, snorkel, life jacket) is provided. Transfers included. Peak season (November–March) books up; rain season (May–October) is quieter but choppier. Group size isn't specified but typically 15–30 per boat.
