Koh Phangan
from Phuket

Koh Phangan: Samui's sister island, 7 miles north of Koh Samui, offers many secluded beaches, which are only accessible by boat, very good snorkelling spots in the North and the West, waterfalls and lush green hills that also guard a beautiful, dense jungle.

On a private yacht trip you will find plenty of pleasant anchorages.
Phangan can be fully explored within 2-3 days, and on full moon nights you can experience the party of your life here - if you like crowds.

Koh Phangan definitely belongs to the best islands near Phuket for boat trips.
