THE CAVE ADVENTURE by GeoAventuras PR in Vega Baja

Vega Baja, a coastal municipality on Puerto Rico’s northern shore, offers more than sun-drenched beaches and vibrant town life—beneath its surface lies a rugged network of caves carved through limestone over millennia. GeoAventuras PR brings these underground landscapes to life with THE CAVE ADVENTURE, a hands-on, guided spelunking experience that invites visitors to enter a world shaped by water, wind, and time.

The caves in Vega Baja feature dramatic calcite formations, winding passages, and pockets where rare troglobitic creatures eke out an existence in darkness. Their composition of karst topography makes for fascinating exploration—sharp stalactites hang overhead while labyrinthine chambers provide a sense of discovery and mystery. As groups wind through narrow corridors and spacious caverns, guides share insights into the island’s volcanic and marine past, revealing how rising seas and shifting tectonics formed these subterranean marvels.
