Dive Briefing
"The dive begins with a descent from the boat onto the reef crest at approximately 5 to 8 meters. Your guide leads you along the reef slope in the direction of the moderate current, descending gradually to 23 to 28 meters. The reef is covered in dense hard and soft corals at every depth, with resident turtles, Napoleon wrasse, and schools of reef fish throughout. The deeper sections feature sandy ledges and overhangs where whitetip reef sharks rest during the day. Throughout the dive, your guide will point out notable marine species and interesting coral formations that you might otherwise miss. The variety of habitats ensures that every minute of the dive offers something new and exciting to discover. Your guide signals the ascent and you work your way back up to the shallower reef at 5 to 8 meters where the coral garden is spectacular in the sunlight. The safety stop is conducted along the upper slope before surfacing near the boat. Total dive time is typically 50 to 60 minutes depending on air consumption and the depth profile chosen."
