Bacuit Bay

Carved from 250-million-year-old Permian limestone, Bacuit Bay’s monumental karst archipelago took shape long before early Austronesian seafaring cultures navigated its labyrinthine channels. By the twelfth century, local Tagbanwa gatherers scaled these sheer, razor-sharp monoliths to harvest the prized gelatinous nests of the edible-nest swiftlet, initiating a lucrative maritime trade route with Song and Ming Dynasty merchant junks. Rising abruptly from the seafloor, the bay’s dramatic topography is crowned by Cadlao Island’s 640-meter jagged peak, while forty-five surrounding islets conceal sunken sinkholes, sheer vertical cliffs streaked with iron oxides, and fringing coral reefs that shelter sea turtles and giant clams. Drifting into the bay aboard a twin-outrigger *banca*, travelers feel the ocean swell subside as the boat glides across water shifting from ink-blue depths to translucent neon-aquamarine. The roar of the inboard engine yields to the echo of dripping water and the shrill calls of swiftlets nesting in cathedral-like limestone fissures. Entering Miniloc Island’s Secret Lagoon requires abandoning the craft to wade chest-deep through a narrow, jagged keyhole in the rock face, suddenly emerging into an enclosed, mirror-still amphitheater walled by blackened, sun-warmed stone. Floating on the saltwater surface, the skin prickles against cool subterranean freshwater springs bubbling up through the floor of this ancient, collapsed cave.
