A low-angled sun warms your shoulders as the boat slips out of Chalong Pier and the Andaman Sea opens into bands of turquoise and deep blue. The Racha (Raya) Islands rise like coral-carved spires off Phuket’s southern coast; by the second glide you’re watching the crew set tanks and brief divers for three guided dives that will take you along sloping walls, sandy basins and sheltered bays.

History
Racha Yai historically served local fishermen and small boat builders; diving tourism grew as operators began mapping its productive reefs in the late 20th century.
Conservation
Coral fragility means operators encourage no-touch diving, reef-safe sunscreens, and strict buoyancy control to reduce damage to fragile colonies.

Check seasonal visibility
Visibility can change by season—ask the operator which side of the island you’ll hit that day for best clarity.
Bring reef-safe sunscreen
Use only reef-safe sunscreen to protect coral and reduce the need to rinse repeatedly after dives.
Prepare for seasickness
Take anti-nausea medication before boarding if you’re prone to motion sickness; the crossing can be bumpy in wind.
Mask fit matters
Bring a well-fitting mask or test one at the start—leaks are the most common discomfort for beginners.
Personal mask and snorkel
A well-fitting mask reduces leaks and improves comfort during surface swims and dives.
Rashguard or wetsuit top
Provides sun protection and warmth for repeated surface intervals between dives.
