Discover more about Poço Azul

Poço Azul is a captivating natural attraction nestled in the heart of Bahia's Chapada Diamantina. This stunning subterranean cave, located near the town of Nova Redenção, is famed for its incredibly clear, azure waters. The cave's interior boasts impressive rock formations, with depths ranging from 3.5 to 16 meters, creating an ethereal and almost vertiginous experience due to the water's transparency. Visitors are invited to float in the cool, mineral-laden waters, an experience enhanced by the sunlight that penetrates the cave between February and October, typically from 12:00 PM to 2:00 PM, casting a spectacular turquoise hue. Life jackets, masks, and snorkels are provided to enhance the viewing experience. Swimmers can observe the various rocks and tree trunks submerged within the lake. Beyond its beauty, Poço Azul is also Brazil's largest submerged paleontological site. Discovered in 1920, the cave gained further significance in 2005 with the discovery of fossils from various animal species, including a near-complete skeleton of a 20-foot-long ground sloth that roamed the Americas until about 11,000 years ago. This has spurred local interest in preserving the cave's paleontological heritage. To preserve the delicate ecosystem, visitors are required to shower before entering the water and are prohibited from using sunscreen or insect repellent. The site operates with specific hours, and it is advisable to plan your visit accordingly.
