Andaman Marine Topography

Archipelago Reefs & Oceanic Drop-Offs

From calm sandy bights at Neil Island to volcanic pinnacles off Havelock, we map bathymetry, current dynamics, and seasonal marine sightings across all major dive sites.

Regional Breakdown

Three Distinct Andaman Dive Zones

HAVELOCK ISLAND

Reef Drop-Offs & Coral Pinnacles

Deep wall sites and oceanic pinnacles ranging from 18 to 30 meters depth. Home to hawksbill sea turtles, barracuda schools, and expansive staghorn coral gardens with moderate current.

NEIL ISLAND

Shallow Coral Bays & Calm Entries

Sheltered sandy seabed entries and high-visibility coral slopes averaging 6 to 12 meters depth. Ideal for calm water entries, first-breath scuba experiences, and macro photography.

PORT BLAIR

Coastal Warmups & Logistics Hub

Fringing reefs and training bays within 15 minutes of port. Serves as the primary archipelago entry point for gear calibration, check dives, and island transfer logistics.
