About this tour
When Jake from our team booked the Similan Islands snorkeling tour with Seastar Andaman, we got a full-day run hitting some of Thailand's best reef sites from Phuket. The outfit runs modern speedboats and plays the conditions day-to-day, picking spots based on visibility and what's showing up — dolphins, turtles, the works. It's an 11–12 hour commitment door-to-door with hotel pickups included, Thai lunch onboard, and enough time to actually breathe underwater at three different spots. The Simlians feel less trampled than some Phuket day-trips, though you're still sharing the water with other tour groups.
Highlights
- Stonehenge site: 25m underwater rocks, proper otherworldly snorkeling geometry
- Honeymoon Bay beach time — actual sand and a break from the boat
- Christmas Point runs turtles and occasional dolphins mid-season
- Modern fleet, decent onboard comfort for a full day at sea
- Thai lunch included, fresh fruit too — beats the usual cooler sandwiches
- Guides speak English, navigate sites based on real-time conditions
- Hotel transfers door-to-door, no separate taxi juggling
What to expect
You're picked up from your hotel in the pre-dawn dark — the boat leaves early to grab the best light and calmest water. The speedboat ride out takes roughly 90 minutes, which is quicker than traditional longtails but feels like it. Once you hit the Simlians, Jake found the three snorkeling stops genuinely varied: Stonehenge is the show-off site with those towering rock formations, Christmas Point is busier but where the sea life tends to congregate, and Honeymoon Bay lets you actually step on sand and shake off the salt for a bit.
The pacing works — three snorkels broken up by lunch and a beach stint means you're not just bobbing in a mask for 8 hours straight. Visibility when Jake went was solid, low-visibility days do happen in monsoon shoulder seasons, and the guides will pivot to different sites if conditions drop. The boat crew handles logistics smoothly: life jackets, fins sorted, snorkel gear rinsed. You're back at your hotel by late afternoon, tired but not wrecked.

Good to know
This tour genuinely offers variety — three different reef characters, actual island time, and the guiding is attentive without being hovering. Small-group feel despite running multiple boats daily. Modern kit beats the creaky-boat lottery.
The national park fee (400 THB per adult, 200 THB per child) isn't in the headline price — factor that in. Early pickup is real, and if you're slow to wake, it stings. The 11–12 hour window includes hotel transfers, so snorkeling time is more like 6–7 hours across three stops. Sea can be rough on occasional days; the tour cancels rarely but it happens. Not suitable if you've had spinal injury, heart conditions, or are pregnant — read the fine print. You need to send your passport to them post-booking for the national park permit; that's their policy, not optional. Bring sunscreen, hat, and reef-safe lotion — coral matters.
Transfers included from most Phuket accommodation. Mask, fins, snorkel, life jacket all supplied. Lunch and fruit onboard. Kids aged 4–11 get a discounted ticket. Public minivans run to the pier if you'd rather avoid the tour transfer. Peak season (Nov–Feb) books up early.
