Diving & Travel Guide to Biak & the Padaido Islands

About Biak & Padaido Islands

Biak and the Padaido Islands lie off the northern coast of West Papua in the deep waters of Cenderawasih Bay and the Pacific Ocean, representing one of Indonesia's most remote and least-explored diving frontiers with extraordinary marine biodiversity and significant WWII historical heritage. Biak Island, the largest in the archipelago, was a major Japanese naval base during WWII and the site of fierce battles during the Allied Pacific campaign, leaving a legacy of wrecks, caves, and military relics that combine with the region's pristine coral reefs to create a uniquely compelling dive destination. The underwater environment is characterized by dramatic wall diving along the island's steep southern coast, extensive coral gardens on the Padaido Islands' sheltered reefs, and the remarkable presence of whale sharks that aggregate in Cenderawasih Bay throughout the year. The Padaido chain, a cluster of small islands south of Biak, offers some of the region's best reef diving with healthy coral systems supporting an impressive diversity of reef fish, turtles, and reef sharks in crystal-clear Pacific waters. The region's isolation in West Papua has preserved both the marine ecosystems and the indigenous Papuan culture, with the Biak people maintaining traditional fishing practices and a strong maritime heritage that includes the distinctive Wor ceremony and seafaring traditions. The whale shark population in Cenderawasih Bay is one of the most reliable in Indonesia, with the gentle giants attracted to the traditional bagan fishing platforms scattered throughout the bay. For the adventurous diver seeking a combination of pristine Pacific diving, whale shark encounters, and WWII history in a genuinely remote setting, Biak and the Padaido Islands deliver an experience that few Indonesian destinations can match. Geologically, the islands are characterized by uplifted limestone reefs, which have created a landscape of dramatic cliffs and deep underwater caves that were utilized by soldiers during the war. This geological history adds a layer of terrestrial wonder to the trip, as many of the best dive sites are positioned right beneath towering limestone walls that drop straight into the deep blue of the Pacific.

Getting There

Biak is served by Frans Kaisiepo Airport (BIK), with connecting flights from Jayapura, Makassar, and Jakarta. The airport was originally built during WWII and remains the main gateway to the region. From Biak, the Padaido Islands are accessible by speedboat charter, taking approximately 1-2 hours depending on the destination island. Cenderawasih Bay and the whale shark sites are also accessible by boat from Biak, with the main bagan platforms approximately 2-3 hours away. The limited tourism infrastructure means that most diving is organized through a small number of local operators or via liveaboard expeditions that include Biak on longer West Papua itineraries.
