Just back from Racha Yai and Racha Noi. Vis was 25-30m, saw reef sharks at Cathedral Rock, only 2 other boats around total. While Anemone Reef offers incredible biodiversity for advanced divers, Racha Islands provide similar quality with more accessibility for all levels.

Racha Yai has Bungalow Bay (10-18m, perfect for Open Water) and Bay 1 (15-28m wall). Racha Noi is advanced - Banana Rock has strong currents but incredible fish life. Cathedral swim-through at 18m is spectacular.

Book with Scuba Cat or Sea Fun from their bases. Full day 3900-4500 baht including 3 dives, gear, lunch. Back by 5pm not 8pm like Similan trips. Perfect when you want convenience without sacrificing marine life quality.
