This dive site, Lucy's Reef, is located on Racha Yai Island, stretching between Bay 3 and Bay 4, heading south. It offers a good opportunity for divers to explore a reef that transitions from shallow to moderately deep water. Navigation involves swimming from Bay 3 towards Bay 4, where vibrant coral beds and various coral formations are encountered in the rocky area at the south end of Bay 3. Strong currents can sometimes make for a swift drift from one bay to the other.
The marine life at Lucy's Reef is diverse, featuring schools of yellowfin snappers and red flounder. A variety of damselfish can be observed among the corals, alongside endemic species like the Coral butterflyfish, unique to the Phuket region. Occasionally, lucky divers may also encounter the majestic whale sharks.
While specific best times to visit are not detailed, Racha Yai generally offers good diving conditions during Thailand's dry season (November to April). The variable currents can be an exciting highlight for experienced divers seeking a drift, but beginners should be mindful of conditions. Its moderate depth makes it suitable for both scuba diving and freediving, with ample coral and fish life for snorkelers in the shallower areas.
