Krabi 4-Islands Sunset Private Speedboat: Snorkel, Beach Walks & Bioluminescent Plankton
Board a private speedboat from Ao Nang in the quiet afternoon, snorkel coral gardens, walk sandbars between islands, watch sunset at Phranang Beach, then search for glowing plankton on a night snorkel. This seven-hour tour blends active marine time with coastal relaxation.
The Experience
Before You Go
Book the late afternoon slot
Departing after midday avoids most day-trip crowds and gives you calmer beaches and better sunset light.
Bring reef-safe sunscreen and a hat
Sun is strong on exposed beaches—use reef-safe sunscreen to protect coral and your skin.
Pack a dry bag and quick-dry towel
Phones and warm layers should stay dry for the evening plankton swim and the return journey.
Heed guide safety briefings
Night snorkeling and open-water swims require life jackets and attentive guides—declare any medical conditions before boarding.

Conservation Note
The national park fee helps fund protection of fragile coral and coastal habitat; avoid touching coral, use reef-safe sunscreen, and follow guide instructions to minimize impact.
The islands sit off Krabi’s coast where limestone karsts formed from ancient marine sediments; the area has long supported local fishing communities and small-scale tourism.
