4 Islands Snorkeling Tour from Ao Nang — Longtail Boat & Tombolo Walk
A classic longtail-boat day trip from Ao Nang that pairs snorkeling with a walkable tombolo and visits to Phra Nang Cave, Koh Poda and Chicken Island. Expect limestone cliffs, clear snorkeling flats, a beach buffet and a guided sandbar crossing at low tide.
The Experience
Before You Go
Bring reef-safe sunscreen
Use reef-safe sunscreen to protect delicate corals and follow guide instructions about reapplication timing.
Wear water shoes
Rocky or shelly shorelines and shallow boat landings make water shoes safer than flip-flops.
Watch tide times for the tombolo
The sandbar between Koh Tub and nearby islets is accessible only near low tide—check with your guide to plan the walk.
Motion-sickness prep
If you’re prone to seasickness, take preventative medication before boarding; boats can be bumpy on windy days.
