The Cueva Alfredo Jahn Natural Monument[1] (Spanish: Monumento Natural Cueva Alfredo Jahn),[2] 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 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.

The monument was named in honor of Alfredo Jahn, a pioneer of various scientific disciplines in Venezuela, such as geography, topography, astronomy, anthropology, linguistics, and botany, and who was also the founder of the Venezuelan Society of Natural Sciences.

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.

[citation needed] 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.
