About this tour
When Ben from our team ran this Seastar Similan Islands snorkel trip from Phuket, we clocked a proper full day on the water — eight hours total, hitting four islands with multiple reef dives. You're speedboating out to some of Thailand's best coral gardens: the Simlans sit maybe 50km offshore and draw a mixed crew of families, couples, and solo travellers keen on both action and lounging. The boat's modern, the guides speak English, and the itinerary stitches together snorkling sites (reef walls, turtle spotting potential), beach time at Princess Bay, and lunch ashore. It's the kind of tour that runs like clockwork most days, though seas and wildlife sightings vary.
Highlights
- Four separate snorkel spots across Islands 4, 5, 6, and 8 in one day
- Iconic Sailboat Rock at Koh Similan — recognisable and swimmable
- Breakfast and Thai lunch included; snacks and water throughout
- Hotel pickup from Phuket saves the early stress of finding your own transport
- Coral gardens dense enough to spot reef fish, occasional turtles
- Princess Bay beach break gives lungs and legs a proper rest
- Guide led us through reef features rather than just dropping us in
What to expect
You'll be collected from your Phuket hotel before dawn — think 6 to 7 a.m. depending on location — then driven to the pier. Light breakfast comes early, then you're on a speedboat for roughly 90 minutes heading out to the national park. First snorkel is usually Islands 5 and 6, where the water's clear and the reef drops off properly; Ben noted the guide pointed out coral bommies and schools of fusiliers rather than leaving you guessing. By mid-morning you're ashore at Princess Bay (Island 4) for a swim and sand time — it's picturesque and calm, a genuine breather. You'll snorkel a second site around Koh Ba Ngu before heading to the main event: Koh Similan (Island 8) where Sailboat Rock sits in shallow water and you can either swim around it or hike to the top for views across the archipelago. Lunch is served on the island — properly prepared Thai curry or rice dishes, nothing fancy but filling. The ride back is gentler; you're onboard by early evening. Timing's tight but not rushed. Transitions between sites happen smoothly, and the guide manages snorkel time so you're not hanging about. Weather can shift — seas get choppy some days — so flexibility helps.

Good to know
This ticks multiple boxes in one day. Reef quality is genuine, not picked-over. Small group feel works because guides actually watch you underwater and steer you toward the best bits. Inclusions cover most of what you need: breakfast, lunch, water, snorkel kit, insurance, and transfers. Works for families (kids can float in a vest), solo travellers, mixed fitness levels. The national park setting means coral rules are enforced, so reefs are healthier than crowded commercial sites elsewhere.
National park fees aren't included — add 400 THB (adult) or 200 THB (child) on the day. Early start (6–7 a.m. pickup) catches a lot of people out. Pregnant guests aren't permitted; those with heart, blood pressure, or bone conditions are flagged as unsuitable, so check before booking. You'll need a copy or photo of your passport/ID to check in — digital photo on your phone works. Seas can be rough; wave-sensitive stomachs should consider travel sickness meds. Group size varies; you won't always get a tiny outfit. Bring reef-safe sunscreen and a rash vest — burns happen fast on the water. Pack a towel and dry clothes for the boat.
Accident insurance, breakfast, lunch, snorkel gear, life jacket, guide, transfers all in. Park fees and lunch drinks extra. No underwater camera rental mentioned; bring your own or go dry.
