Racha Island (Raya Island): Phuket’s Underwater Backyard
A day on the clear water between Phuket and Raya—snorkels, dives, dolphins, and private boat freedom
The boat nosed into a basin of impossible blue and everything on deck slowed. Sea spray smelled of salt and pulled lime; the engine’s chatter became a steady heartbeat. On the bow, a pair of sunburned travelers traded a quiet, reverent look—the sort of small communion you only get when land drops away and the only horizon belongs to water. This is Racha Island (Raya Island): two sister isles that sit like prisms in the Andaman Sea, just south of Phuket, and they demand a different kind of attention. They ask you to slow down, to breathe, and to remember that color can be sound.
Trail Wisdom
Choose your vessel to match your pace
Speedboats maximize time across multiple islands; catamarans prioritize comfort, shade, and a stable platform for snorkeling and sunsets.
Bring reef-safe sunscreen
Healthy reefs depend on it; choose mineral-based sunscreen and reapply only in the shade or on the boat.
Book morning departures
Early starts often mean calmer seas and better visibility for snorkeling and diving.
Pack a dry bag and a light layer
A dry bag keeps phones and cameras safe; a light long-sleeve blocks sun on the open deck.

Conservation Note
Many operators now promote reef-safe practices and limit anchor damage by using mooring buoys—choose companies that follow local reef-protection rules.
The Racha islands were long used by local fishermen before tourism developed; their reefs and channels were important local fishing grounds.
