Key Hazards
Boat trafficStrong current
Safety Notes
Watch the current outside the bay, keep the rock line in sight, and treat the swim-throughs as a buoyancy exercise rather than a race.

Certified scuba divers are the right baseline; the outer rock is not a casual shore-snorkel site.

Follow Phuket operator guidance and any marine-park instructions for the Racha islands.
