Key Dive Site Facts
Dive Site Overview
Small Wall's topography unfolds from an expansive coral reef, originating directly at the surface, into a dramatic underwater landscape. Frequently described as a 'huge coral reef,' a distinct wall section typically slopes from around 4 meters (13 ft) down to 30 meters.
Dive explorations here can extend to a considerable maximum depth of 50 meters. At approximately 30 meters, divers discover a secondary drop-off, where a vibrant and complex environment comes to life. Rich diversity in colorful corals and intricate gorgonians forms a striking display along this deeper section.
Numerous species of hard corals make up the reef itself, exhibiting a wide range of shapes and hues, from robust plate corals to delicate branching formations. These structures provide essential shelter and sustenance for countless marine organisms.
Such compelling topography, transitioning from sun-drenched, fish-filled shallows to its more dramatic deep-wall features, ensures an engaging experience for all certified divers, from recreational enthusiasts to technical exploration specialists.

Water visibility usually reaches its peak from September to November, frequently ranging between 30 to 40 meters (98 to 131 feet), offering extensive views of the wall's grandeur. Warmer water temperatures are typically encountered from December to March, making these months especially appealing.
