    Dive Briefing

    "The dive at Bubbles (Hot Springs) begins with entry from the boat or shore with a short surface swim to the descent point marked by the reef edge or wall. After a controlled descent to approximately 7 meters, divers explore the main reef structure where the current-facing sections offer the best marine life encounters in the nutrient-rich waters of the Coral Triangle. Mandarin Fish are frequently observed patrolling the reef at depth, while Grouper inhabit the coral gardens, overhangs, and ledges throughout the mid-section of the dive profile. The site features a variety of bottom compositions and structural elements that support diverse marine communities and provide excellent opportunities for both wide-angle and macro observation. Your guide leads you progressively shallower along the reef contour, ensuring adequate bottom time for the safety stop at five meters. Mandarin Fish, Grouper, Lionfish, Rhinopias are commonly encountered throughout the dive at various depths and habitats. The final portion of the dive is spent exploring the shallow reef area at 2 to 10 meters where biodiversity is highest and sunlight creates ideal conditions for photography. The safety stop is conducted along the upper reef before surfacing for a total dive time of approximately 45 to 55 minutes. Bubbles (Hot Springs) consistently delivers memorable diving experiences for visitors to Berau."
