About this tour
When Sarah from our BugBitten team tried this seven-island snorkel run out of Krabi, she found herself on a shared boat threading between limestone karsts, dipping into the Andaman Sea, and finishing with dinner as the sun dropped over Poda Island. You're island-hopping to spots like Chicken Island and Railay Beach, with a night snorkel thrown in to catch the bioluminescent plankton — that eerie green glow when you move through the water. It's a full-on 7-hour push, so come ready for heat, salt water, and a decent amount of time in a boat with other tourists.

- Seven island stops, each with different snorkel spots and beach vibes
- Sunset dinner on Poda Island with views across the Andaman

- All snorkel gear and life jackets supplied; no hiring extras
- Professional guide handles safety and spot knowledge throughout
- Hotel pickups cover Aonang, Krabi Town, and Klong Muang areas
- Buffet dinner and drinking water included, plus seasonal fruit
What to expect
You'll be picked up from your hotel early, then herded onto a shared longtail with a handful of other travellers. The boat moves between islands at a steady clip — expect to spend as much time motoring as you do swimming. Each stop gives you 20–40 minutes to snorkel or float; the water's warm, visibility can be patchy depending on weather, and you'll see reef fish if you're lucky. Sarah noted the boat can feel crowded, especially during peak season, and seasickness is a real risk if the Andaman's rough.
Dinner lands around late afternoon on Poda Island — a simple but filling buffet with soft drinks and water. Once the sun's down, you head to Railay Beach for the night snorkel. This is the drawcard: you'll see tiny plankton light up as you move through the water, creating a ghostly green trail. It's genuinely odd and worth the trip, though conditions vary and sometimes the glow's faint. You'll be back at your hotel by 11 p.m. or so, tired but buzzing.

Good to know
If you want to island-hop without renting a private boat, this covers a lot of ground in one hit. The bioluminescence night snorkel is the standout — nothing else on Krabi's snorkel menu offers that. Professional guide, safety gear, and dinner included mean fewer surprises. Suits active travellers aged 18–65 who don't mind boat time and a full-day pace.
It's a shared boat, so you're packed with strangers and moving on a set schedule. Seasickness is common in the Andaman; bring tablets or a patch. The tour excludes two of the named islands (Poda and Tub Island), so check the actual itinerary. Early start, strong sun, and 7 hours solid mean this isn't a laid-back day. Not suitable for pregnant travellers, anyone with spinal or cardiovascular issues, or those with poor fitness. Peak season (November–February) gets rammed. Bring reef-safe sunscreen, a rash guard, and cash for tips.
