About this tour
When Mia from our team joined SeaStar Andaman's Similan Islands snorkel run, we found ourselves on a 10-hour sprint from Phuket to some genuinely solid reef spots. The outfit runs modern speedboats and tweaks the day's plan based on actual sea and weather conditions — which matters when you're chasing corals. They follow Green Fins protocols, so there's a real effort to keep the reefs alive rather than just bash through them. The crew are bilingual and fairly switched on, and you get breakfast, lunch, gear, insurance and a hotel pickup as part of the package. It's a solid day on the water if the conditions play along.

- English and Mandarin guides mean better explanations underwater
- Thai lunch box beats the standard sandwich-in-a-box fare
- Small-group feel — guides adjust to your pace and interests
- Insurance and first aid kit provided as standard
What to expect
You'll be picked up from your Phuket hotel early — expect a pre-dawn start. The speedboat ride to Similan takes about 90 minutes; it's smooth but you'll feel the pace. First snorkel usually happens mid-morning at a site chosen that morning based on wind and swell. You'll get a light breakfast beforehand and fresh fruit between sessions. The reef itself is the draw — visibility varies, but when it's clear the coral and fish life are genuinely worth the trip. Mia found the guides patient about pointing out life rather than rushing through. You'll do two or three snorkel drops depending on conditions, with a proper Thai lunch box midday. Afternoon snorkelling finishes by early-afternoon, then the boat ride back. It's a long day but broken up enough that fatigue doesn't kill it.
The pace is deliberate rather than rushed. You're not cramped on a cattle-boat, and the crew seem to actually care about the reefs staying alive — you'll see that in small things like where they anchor and how they brief you on staying off coral. If the sea's choppy, don't be surprised if the plan changes or a site gets swapped; that's the trade-off for chasing the best conditions.

Good to know
If you snorkel regularly or want to see Thai reefs without the Phi Phi circus, this delivers. The reef quality is several notches above the tourist mill closer to Phuket. Small groups mean your guide actually spots things for you. Lunch and all gear included keeps costs transparent. Bilingual guides help — you get real info, not just "fish, yes?" and a wave.
The early start is real; you're leaving before sunrise. The boat ride is smooth but 10 hours on water suits people who don't get queasy. Not suitable if you're pregnant, have spinal issues, or poor cardiovascular health — they're clear about this upfront. Bring your passport ID page in digital and physical form (Thai Marine Department requirement). Remote villa pickups aren't covered, so you'll need hotel or main-road access. Peak season (November–April) means crowds at popular sites; shoulder season is quieter but sea conditions less guaranteed.
reef-safe sunscreen, a rash guard, any prescription meds, seasickness tablets if prone, and a waterproof bag for valuables. Towel's provided. The tour's subject to weather and sea changes, so book flexibility into your plans.
