Exploring Koh Kong (island)#

Koh Kong Island lies a few kilometres offshore in the Gulf of Thailand, in the southwest of the province of the same name. Roughly 16 km long and 6 km wide, it is ringed by quiet white-sand beaches and remains largely undeveloped, making it a popular spot to swim, fish, snorkel and simply unwind for a few days.

The provincial capital, Koh Kong town, is the first port of call from Thailand and the usual jumping-off point for boats to the island. There is little to do beyond walking, swimming and eating, but a scattering of resorts and Western-run bars and restaurants provide enough comfort for a relaxed stay; the rest of the island is easily explored by motorbike.

How to Get to Koh Kong (island)#

Koh Kong province has boat services to nearby islands from the mainland. Travel to Koh Kong town (by road from Phnom Penh) and arrange boat transport to outlying islands-local skippers know the safest routes.

Tips for Visiting Koh Kong (island)#
