Cueva Ventana, Protected area in Arecibo, Puerto Rico.
The limestone cave system contains multiple chambers with natural formations, including stalactites and stalagmites, leading to a natural window overlooking Rio Grande valley.
The Department of Natural and Environmental Resources acquired the land surrounding the cave in 2012 to prevent vandalism and preserve its geological features.
The cave gained international recognition after being featured in multiple productions, including Disney Channel's Wizards of Waverly Place and the British series Treasure Island.
Visitors must participate in guided 90-minute tours, which include safety equipment, flashlights, and expert information about local flora and fauna.
The cave entrance features ancient petroglyphs and houses colonies of bats, while its final chamber opens to a natural window with views of the valley.

Puerto Rico offers more than the beaches and colonial fortresses of San Juan. The island contains dozens of natural swimming pools, remote coastal sections and protected forest reserves. The northern coast holds limestone caves with pre-Columbian petroglyphs, while the southwest region includes bioluminescent bays and extensive salt flats. The interior features waterfalls cascading over volcanic rock and hiking trails through mountain canyons with native vegetation. Historic sites include 19th-century lighthouses on rocky promontories, Spanish fortifications guarding harbor entrances and archaeological sites like the indigenous ceremonial center of Tibes near Ponce. Coastal areas offer natural swimming holes separated from the sea at low tide, including Las Paylas in Luquillo and Pozo de Jacinto in Isabela. The dry coastal forests of Guánica and the wet rainforest of El Yunque show the range of the island's ecosystems. Visitors reach these locations via local roads that are often unpaved and poorly marked. Many natural pools and waterfalls require short hikes over uneven terrain. The best conditions occur during the dry season from December through April, when river flows run lower. Some locations like Reserva Natural Las Cabezas de San Juan require advance booking for guided tours, while others remain freely accessible year-round.
