Koh Rai is the furthest island from the mainland and the least visited. Very few tours make the extra journey out here, which means you're likely to have the place almost entirely to yourself. That alone makes it special.
The reef around Koh Rai is largely undisturbed. The snorkeling here has a different quality, bigger formations, more fish and a sense of genuinely exploring something untouched. Hawksbill turtles have been spotted regularly on the northern side.
The beach is small but beautiful, and the backdrop of limestone cliffs makes for incredible photos. A stop here is only included on the speedboat and private tours.
Koh Rai is included on the full speedboat and private tours.
Only the full speedboat tour and the private charters go out that far, and even then it is weather permitting. The captain decides on the morning, because it is the most exposed island in the group.
It is the furthest island from the mainland, so a stop costs a meaningful amount of the day in travel time. Most joined itineraries would have to drop another island to include it, which is exactly why it stays quiet.
The reef is less disturbed, with bigger formations and more fish than the busier stops, and hawksbill turtles are seen regularly on the northern side. Nothing is guaranteed with wild animals, but Koh Rai is the best chance of a quiet reef in the group.
On a private charter, yes: tell the captain at the pier and he will build the day around it if the sea allows. On a joined tour it is added when conditions are right rather than on request.
No. There are no facilities, no shops and no toilets, which is part of the appeal and worth planning around. Hong Island is the stop with toilets and changing facilities.
Koh Rai sits in the Krabi marine national park, just off the coast of Ao Nang.
