Key Dive Site Facts
Dive Site Overview
Mangrove, situated on Nusa Lembongan's northern coastline, unfolds as an expansive coral plateau, directly adjacent to a significant mangrove region. A shallow Formosa staghorn coral garden marks the beginning of the dive, where vibrant hues of branching corals are especially striking, benefiting from ample sunlight in minimal depths.
As divers proceed, the gentle slope guides them into progressively deeper water, revealing a rich arrangement of hard and soft corals. Numerous bommies, scattered across the reef, serve as natural landmarks and provide additional habitats, enhancing the diversity along the descent.
This site offers a comprehensive look at a healthy ecosystem, vividly demonstrating the crucial role mangroves play in supporting the vitality and quality of local coral communities. Descending gradually, divers can explore down to a maximum depth of 40 m (131 ft), encountering enormous barrel sponges, intricate soft coral formations, and an array of colorful sea fans clinging to the reef.
Consistent nutrient flow from the adjacent mangroves nurtures a thriving underwater scenery, inviting divers to float effortlessly through well-preserved sections. It's a truly diverse environment, blending shallow, sunlit gardens with deeper, richly structured slopes.

Dive Experience & Conditions
Current dynamics at Mangrove are generally moderate to mild, influenced by tidal movements and the lunar cycle. Divers can expect a gentle river-like flow, ideal for drift diving, allowing for a relaxed exploration of the sloping reef. Visibility typically extends up to 30 meters. While suitable for all certification levels, less experienced divers might focus on shallower sections, which typically range from 10-25 meters deep. When encountering windier conditions, maintaining neutral buoyancy and facing the bottom helps stabilize the dive. This site generally offers calm entries by boat, which is the standard approach.
Dive Difficulty & Safety Guidelines
Ensuring a safe dive at Mangrove requires attention to buoyancy and current awareness, especially during drift dives. Although the currents are typically mild, they can vary, so divers should always remain attentive to their dive guide's instructions. Novice divers are advised to stay within the shallower, more protected areas of the site to acclimate to conditions. Maintaining a safe distance from the coral structures is crucial to preserve the extensive reef and prevent accidental contact. It's also important to monitor your bottom time and air consumption, particularly when exploring deeper sections or during longer drifts.
