You feel the boat lift and the Andaman Sea open around you: sun on your shoulders, the island’s tree-lined profile sharpening as the speedboat cuts toward Kahung Beach on Koh Hey (Coral Island). The water ahead is a range of greens and blues, and the reef waits, flirtatious and bright.
Koh Hey sits just off Phuket’s southeastern shore and has long been a local fishing ground turned day-trip playground. Geologically the island is limestone and sandstone fringe with fringing coral outcrops; tidal flow scours the shallows and concentrates the reef life in pockets that snorkelers love. The island’s tourism is recent—centered on day visitors from Phuket—so remnants of local fishing culture still mark the shore.
Expect three hours on the island: snorkeling over shallow reefs, swims from white-sand Kahung Beach, and optional pay-as-you-go thrills like parasailing or banana boats. Guides provide life jackets and basic snorkel gear; seasonal fruit and drinking water are usually included. Weather and sea conditions govern visibility and comfort—calm mornings deliver the best underwater clarity.
Practical guidance: bring reef-safe sunscreen, a snug mask (rental quality varies), and reef shoes for jagged patches. Time your trip in the dry season (November–April) for steady seas and the clearest water. If you’re new to snorkeling, floatation helps—staff are experienced with beginners but basic swimming ability is required. Leave no trace: avoid stepping on or touching coral and pack out plastics. With sensible prep, this half-day speedboat run is an efficient, high-reward introduction to Phuket’s coral reefs.
