Alor: Pantar Strait Dive Site – Alor Archipelago

Site Overview

The Pantar Strait is the narrow channel between Alor and Pantar islands, approximately 40 minutes by boat from Kalabahi, where powerful tidal currents create one of the most biodiverse marine environments in the Alor Archipelago and all of eastern Indonesia. The strait funnels strong currents between the islands, generating nutrient-rich upwellings that sustain prolific coral growth and attract large pelagic species from the deep waters of the Flores Sea. The dive sites encompass multiple locations along the strait, featuring vertical walls dropping from 3 meters to beyond 40 meters, coral-encrusted pinnacles, and overhanging ledges sheltering diverse marine communities. The strong current keeps the hard corals exceptionally healthy, with massive table corals, dense staghorn formations, and large barrel sponges dominating the shallower sections. The wall sections at 10 to 20 meters are covered in sea fans, soft corals, and crinoids, with grey reef sharks, whitetip reef sharks, and eagle rays patrolling the current. The channel flow brings regular encounters with dogtooth tuna, giant trevally, schools of barracuda, and seasonal hammerhead sharks at 20 to 35 meters. Napoleon wrasse, bumphead parrotfish, and hawksbill turtles are resident throughout the reef system. The deeper sections at 25 to 40 meters feature overhangs where whitetip reef sharks rest, and the current-swept pinnacles are encrusted with colorful corals. The Pantar Strait is best dived from April through October during the dry season. The strait is considered one of the premier dive locations in the Alor Archipelago, attracting experienced divers seeking world-class current diving and pelagic encounters.
