Craggy Island – Diglipur & North Andaman Dive Site
Site Overview
Craggy Island is the most exciting dive site in the Diglipur and North Andaman region offering an exposed offshore reef environment where moderate to strong currents bring abundant nutrients that attract impressive pelagic species and support healthy coral ecosystems in the clear tropical waters of the northern Andaman Sea. The reef slope descends from 6 meters along the shallow reef crest to a maximum depth of 28 meters across dramatic rocky pinnacles, coral bommie formations, and sandy channels that create diverse habitats for both reef-dwelling and pelagic marine species throughout the exposed island reef system. Giant trevally patrol the reef perimeter in impressive numbers while grey reef sharks cruise the deeper base sections hunting for prey in the current-swept environment. Seasonal eagle rays glide between the rocky pinnacles during their migration from January to April adding to the extraordinary pelagic diversity found at this exposed offshore location. Napoleon wrasse cruise the shallower reef slopes and schooling barracuda form tight formations above the reef crest in spectacular numbers. The exposed offshore location means that currents are typically stronger than at the sheltered Smith and Ross Island sites but this brings the nutrients that sustain healthier coral growth and attract the largest concentration of pelagic species found in the North Andaman diving area. The combination of exciting pelagic encounters, varied reef topography, and the adventure of diving at an exposed offshore location makes Craggy Island the premier advanced dive site for experienced divers seeking big animal encounters in the Diglipur and North Andaman region.
Dive Briefing
"A typical dive at Craggy Island begins with entry from the dive boat at the shallowest reef crest at approximately 6 meters allowing divers to orient themselves and assess the current strength before beginning the descent along the exposed offshore reef slope. Once established on the reef divers should swim along the perimeter at 14 to 24 meters depth where the pelagic species are most commonly encountered while maintaining excellent buoyancy control and situational awareness of the current direction and strength throughout the dive. Deploy your reef hook on the up-current side of the reef to maintain position and observe the pelagic action in the surrounding blue water without exhausting your air supply fighting the current. The most productive depth zone is between 16 and 24 meters where giant trevally, grey reef sharks, and seasonal eagle rays are most commonly encountered patrolling the reef edges and sandy channels between formations. Navigate along the slope watching for schools of barracuda in the blue water and check the rocky overhangs and bommie crevices where napoleon wrasse and giant groupers shelter during the day. Monitor depth and NDL carefully particularly below 22 meters on the deeper reef sections and always maintain conservative ascent rates given the distance to the Port Blair hyperbaric chamber. Conclude the dive on the shallower reef crest enjoying the abundant coral gardens before completing a safety stop at 5 meters deploying your DSMB before surfacing near the dive boat."

Safety & Hazards
- Moderate to strong currents along the exposed reef requiring drift diving skills
- Deeper sections to 28 meters requiring careful NDL management
- Boat traffic requiring continuous SMB deployment during drift diving
- Variable thermoclines at depth affecting exposure and requiring appropriate thermal protection
- Exposed location requiring weather assessment before departure and conservative dive planning
Traveler Notes
Who is this for?
Craggy Island is suitable for Advanced Open Water certified divers comfortable with moderate to strong currents and depths to 28 meters along the exposed offshore reef formations. The site rewards experienced divers with exciting pelagic encounters including giant trevally, grey reef sharks, and seasonal eagle rays in an exposed diving environment. Underwater photographers will find outstanding wide-angle opportunities with dramatic reef topography, diverse pelagic species, and excellent visibility during the peak season from November to May. The varied depth profile allows both wide-angle pelagic photography and reef landscape capture making Craggy Island a versatile destination for experienced underwater photographers visiting the North Andaman region.
For Non-Divers
Non-divers can trek to Saddle Peak the highest point in the Andaman Islands, walk across the famous Ross and Smith Island sandbar at low tide, visit Lamiya Bay Beach, and enjoy bird watching on Alfred Island.
