When it comes to coastal cave adventures, Puerto Rico’s sea caves are top-tier. Found along its stunning coastline, these caves are formed by centuries of erosion from the ocean. The underwater caves of Fajardo and the Cueva Ventana (Window Cave) in the north offer jaw-dropping views of the Caribbean Sea.
Whether you’re kayaking through secluded grottos or hiking up to see the majestic openings, Puerto Rico’s caves are both a geological wonder and an adventure playground, perfect for those seeking both relaxation and excitement.
