Frans Kaisiepo Airport — Biak, Indonesia

Frans Kaisiepo Airport serves Biak, an island off the northern coast of Indonesia's Papua region, at a low elevation of 46 feet with a single runway. Biak sits out in the Pacific, north of New Guinea's mainland, making it one of Indonesia's more remote inhabited islands. The airport supports domestic connections within Indonesia along with occasional longer-range traffic, since its runway was originally built to accommodate larger aircraft than a typical regional Indonesian field needs. Papua's geography includes some of Indonesia's most isolated communities, and air travel plays an outsized role connecting islands and coastal towns that lack road or rail links to the rest of the country. Biak's tropical island setting and coral reef surroundings also draw a modest but steady stream of diving-focused visitors.
