Dive Site Overview
Providing a straightforward yet rewarding dive experience, Thalassa House Reef accommodates a range of certification levels, from Open Water to more advanced divers focusing on specific skills. Easy beach entry characterizes access to this site, situated directly from the shore on Lembeh Island.
A gentle sandy slope defines the primary underwater feature, extending to a maximum depth suitable for recreational diving, often around 15-20 m (50-65 ft), though deeper sections may be explored. This slope gradually descends, interspersed with coral rocks and scattered debris that offer shelter for various creatures. Here, an artificial reef has been been established through concrete structures and other installations, creating additional habitats and numerous points of interest for macro observation.
Divers can also refine Peak Performance Buoyancy skills using a specific pipe structure, thoughtfully placed in a controlled environment. Throughout the dive, exploration within this recreational depth range is encouraged, revealing a fascinating array of smaller marine inhabitants typical of the area.
It's an ideal location for multiple dives; each visit potentially unveils new details amidst its carefully developed underwater landscape, inviting thorough scrutiny.
