You push off from Chalong Pier as the morning light slices across the Andaman; the boat hums, coffee steams, and the sea opens toward Racha Yai’s clear bays. By the first descent you feel the pull of a slow current and the world below rearranges into color — hard corals clinging to sloping rock faces, schools of tropical fish fanning out like living flags, and occasional shadows of rays gliding over sand.

Racha Yai (Racha Island) sits a short boat ride south of Phuket. Geologically the islands are low granite outcrops with steep underwater drop-offs that create the “swimming pool” clarity around Homerun Bay and Siam Bay. Historically these waters were local fishing grounds; today small-scale dive operations balance tourism with respect for reef systems.
Expect three guided dives over an eight-hour day; the east coast bays (Bay 1–5) are best for gentle drift dives along rocky slopes at 20–25 m, where nutrient-rich currents attract bigger schools and occasional leopard or blacktip reef sharks and large rays.
Practicalities: this trip requires current open-water certification and basic buoyancy skills. Pickup from Phuket hotels (around 7:15 a.m.) and returns same day; breakfast, snacks, lunch, bottled water and standard scuba kit are provided. Visibility is seasonal — typically clearest in the dry season (Nov–Apr) and more variable during monsoon months. Bring your certification card, logbook, and reef-safe sunscreen, and plan for an 8-hour day with periods of waiting between dives. Surface intervals, briefings, and safety stops are standard; if you have recent medical concerns, consult your physician before travel.

Racha Yai has long been used by local fishermen; modern dive tourism expanded as access from Phuket improved, focusing activity around clear bays and steep reef faces.
Coral reefs here are sensitive to anchoring and sunblock chemicals; operators commonly use mooring lines and encourage reef-safe sunscreen and no-touch practices.
