North Lombok: Medana Bay Dive Site – Lombok
Site Overview
Medana Bay is a sheltered bay on the north coast of Lombok that offers one of the most accessible shore diving experiences in the region. The bay features a gentle slope of coral reef, seagrass beds, and volcanic sand descending from 2 meters to approximately 18 meters, creating a diverse underwater landscape that supports a fascinating variety of marine life. The site is particularly known for its macro critters, including blue-ringed octopus hiding among the coral rubble, colorful mantis shrimp patrolling the sand channels, and seagrass ghost pipefish swaying in the gentle current. The sheltered geography of the bay provides protection from the prevailing swells, making it diveable in conditions that would close other sites along the coast. Medana Bay is one of the few shore-accessible dive sites in Lombok, with a short swim from the beach bringing divers directly onto the reef. The site is also popular for night diving, when the seagrass beds and coral reef transform with the emergence of hunting octopus, squid, bioluminescent organisms, and nocturnal crustaceans. The mix of habitats, from coral bommies to seagrass meadows to volcanic sand slopes, ensures that each dive offers something different. Medana Bay is also a favored training site for local dive operators, with its easy access, gentle slopes, and reliable conditions making it ideal for Open Water courses and check-out dives.
Dive Briefing
"The dive begins with a shore entry from the black sand beach, where you wade into the water and descend to the gentle slope at approximately 3 to 5 meters. The seabed is a mix of coral bommies, seagrass patches, and volcanic sand, creating a varied landscape to explore. Your guide leads you along the slope, working gradually deeper as you search the transitional zones between habitats for interesting critters. At 8 to 12 meters, the coral coverage increases with larger bommies covered in soft corals and anemones. Mantis shrimp are commonly spotted at the entrances of their burrows in the sand. The deeper sections at 15 to 18 meters feature scattered coral heads and seagrass beds where blue-spotted stingrays rest. The return leg follows the shallower reef at 5 to 8 meters, where the macro life is most abundant. The safety stop at 5 meters is spent among the shallow coral bommies with clownfish in their anemones. For night dives, the same route reveals a completely different ecosystem with hunting octopus and bioluminescent displays."
