About this tour
When Mia from our BugBitten team booked the 7 Islands Tour in Krabi, she was after the full day experience — islands, snorkelling, and that famous bioluminescent show. The tour hits seven different spots across the bay, mixing boat time with beach stops and a sunset picnic, finishing with a night snorkel where dinoflagellates glow under your fins. You pick your vessel: a speedboat if you want pace, or a longtail for something more relaxed. The whole thing runs eight hours, so it's a full commitment, and the water conditions matter — if the sea's rough or the plankton aren't cooperating, expectations shift fast.
Highlights
- Speedboat or longtail choice shapes your whole vibe.
- Chicken Island's striking limestone rock — genuinely photogenic.
- Tub Island's natural sandbar connects at low tide.
- Sunset picnic on Railay includes fruit and water.
- Bioluminescent plankton glow happens at night (weather dependent).
- Snorkel gear and life jacket supplied, no rentals.
- Seven separate islands mean constant scenery changes.
- Mix of pristine beaches and quieter bays explored.
What to expect
Your day starts with a boat pickup and heads straight into island hopping. Ma Tang Ming and Puya Bay are gentler stops — mostly wading, swimming, and soaking in the quiet. Poda Island feels busier, as it's a classic Krabi spot, but the powdery sand is legitimate. Chicken Island is short and sweet — you'll see why it got its name, take your photos, and move on. Tub Island's the surprise: if the tide's right, you can walk the sandbar between two larger chunks of rock, which feels oddly magical. Around sunset, the crew sets up a picnic on Railay with fresh fruit and drinks. The real event is the night snorkel: you'll head out into calm, shallow water where bioluminescent plankton light up when they move — genuinely eerie and brilliant. The catch? It only works if conditions align and the plankton are active; calm seas are non-negotiable.

Good to know
Eight hours is long enough to feel immersive without feeling rushed. Snorkel kit and life jacket are included, so no extra rental costs. The sunset picnic is a solid touch, and the bioluminescent snorkel is genuinely unusual — worth doing if you're in Krabi. Small to mid-size groups mean you're not crammed in with a hundred others.
You'll pay an extra 200 baht (per adult) national park fee on the day — not mentioned upfront, so budget for it. The tour isn't suitable if you have back problems, are pregnant, or have cardiovascular concerns; it's more physical than it sounds. Early starts are typical, so expect a pre-dawn pickup. Rough seas cancel the bioluminescent snorkel without warning. The islands themselves can get touristy, especially Poda and Railay. Fair bit of time on the boat, so seasickness medication might be wise if you're prone to it. Bring reef-safe sunscreen — the sun reflects hard off the water.
