The Cueva Alfredo Jahn Natural Monument (Spanish: Monumento Natural Cueva Alfredo Jahn), also known as the Alfredo Jahn Cave Natural Monument or Tapa de Cambural Cave, is a protected area with the status of a natural monument that is located 4 km west of the town of Birongo, Miranda State, at the eastern end of the Coastal Range of the Cordillera de la Costa. With a 4.29 km gallery development, it is the largest cave in central Venezuela, the sixth in Venezuela, and one of the most visited caves in the country.
It was decreed as a Natural Monument on December 12, 1978, with Decree No. 2989 published in Official Gazette No. 2,417 of March 7, 1979. The monument was named in honour of Alfredo Jahn, a pioneer of various scientific disciplines in Venezuela, such as geography, topography, astronomy, anthropology, linguistics, and botany, who was also the founder of the Venezuelan Society of Natural Sciences.
It is a moist cave, still active, which has been formed by the action of the Cambural Gorge. Its calcite walls are covered with spectacular stalagmites, stalactites, and columns, which reach their maximum development in the Hall of the Chaguaramo, or Hall of the Rain.
The temperature inside the cave ranges between 22°C and 26°C. The cave is surrounded by a pre-montane seasonal semideciduous forest and presents three dense tree layers.
The area is part of a national park.
