This dive site is the house reef of the Marriott Merlin Beach Resort & Spa, offering convenient shore access directly from the beach. Diving is contingent on high tide, requiring a minimum water level of 1.5 meters for safe entry and exit. Divers must undertake an approximate 100-meter swim across the tidal zone to reach the reef crest, where the dive typically begins at a depth of about 2 meters. The reef itself is relatively shallow, with a maximum depth of 11 meters.
While the description doesn't detail specific marine life, a typical Thai house reef like this would feature various hard and soft corals, providing habitat for an array of small reef fish such as damselfish, butterflyfish, and parrotfish. Macro enthusiasts might spot nudibranchs, crabs, and shrimp hidden among the coral formations. It's a good spot to observe the diverse ecosystem of a healthy shallow reef.
The best time to visit is strictly during high tide, which is crucial for accessibility. It is highly recommended to consult local tide tables before planning your dive or snorkel. This site is particularly well-suited for beginner divers due to its shallow depths and calm conditions. Freedivers and snorkelers will also enjoy the accessible reef crest and vibrant shallow areas, provided they are comfortable with the surface swim to the reef.
