Spend a full day exploring Coral (Koh Hei) and Racha (Koh Raya) islands by catamaran from Phuket — snorkeling, a beach lunch, optional water sports and a sunset fishing stop. Ideal for travelers who want accessible marine life viewing and a relaxed island circuit.

The catamaran cuts through the Andaman like a marker along the horizon as Phuket recedes and two small island worlds grow larger: the sugar-white strips of Coral (Koh Hei) and the rocky headlands of Racha (Koh Raya). Morning pickup at Chalong Pier is brisk; by late morning the salt air and a steady breeze set the pace for a 7–8 hour circuit of beaches, reefs and a slow sunset off the stern.

The catamaran cuts through the Andaman like a marker along the horizon as Phuket recedes and two small island worlds grow larger: the sugar-white strips of Coral (Koh Hei) and the rocky headlands of Racha (Koh Raya). Morning pickup at Chalong Pier is brisk; by late morning the salt air and a steady breeze set the pace for a 7–8 hour circuit of beaches, reefs and a slow sunset off the stern.
Geology here is simple and obvious — limestone outcrops and volcanic basement create shallow reefs that host coral gardens on gentle slopes. Historically these islands have been fishing grounds and occasional shelter for merchants; today they balance small-scale tourism with local livelihoods. Culture on board favors informal camaraderie: guides who point out reef topography, crew who rig snorkeling gear, and local fishers who still ply the channels.
Practical notes are straightforward: expect multiple boat transfers (catamaran to longtail), guided snorkeling in Kon Kae, Siam and Patok Bays, and a shore stop for lunch on Coral Island. Water visibility is best in the dry season; life jackets are required during swims. Bring reef-safe sunscreen, a reusable water bottle, and a mask if you prefer your own fit.
Timing matters — aim to arrive at Chalong early to avoid traffic and secure shade on deck. On the water, currents can shift quickly; listen to crew briefings and keep sessions short if you’re new to open-water snorkeling. With moderate sea conditions and a flexible itinerary, this trip delivers accessible marine encounters and a reliable sunset finish without demanding technical skills.
Travel time varies by sea conditions but plan on roughly 30–60 minutes to each island from Chalong Pier depending on boat type.
Yes — basic snorkeling equipment and life jackets are included, but many travelers prefer to bring a personal mask for fit and clarity.
Families are welcome; infants must sit on laps and life jackets are required — non-swimmers should stay in shallow guided areas or on the boat during snorkeling sessions.
Typical inclusions are hotel pickup/drop-off in Phuket, lunch, snorkeling equipment, admission fees and an English-speaking guide; optional water activities may cost extra.
