Koh Racha

Koh Racha is one of Thailand’s easiest islands to access as it’s located just a short distance from Phuket. Despite it’s proximity to one of Thailand’s busiest tourist destinations, Koh Racha is a wonderful place to escape the hustle and bustle. One of the highlights of Koh Racha is that it offers good shore diving options for those who really want to take it easy and just dive from the beach.

The Similans arguably offer some of the best dive sites and coral reefs in Thailand. Whale sharks, manta rays and other pelagics are spotted here and while a liveaboard may require more advance planning, it’s definitely worth the extra effort!
