Bus di Tacoi, Natural cave in Gromo, Italy.
Bus di Tacoi is a cave located on Redondo Mountain at 1500 meters elevation with ascending and descending routes featuring multiple climbing sections. The underground passages and chambers create a complex network that defines the entire structure of this geological formation.
The cave formed over millions of years through limestone erosion that gradually carved out underground passages. This geological process created the network of chambers and routes that visitors explore today.
The name comes from the Bergamask language and refers to mountain sparrows whose calls echo near the entrance. These bird sounds gave the cave its distinctive local name.
Inside temperature stays at a constant 10 degrees Celsius, so visitors should bring warm clothing and prepare for complete darkness and high humidity. A lamp or headlight is essential for navigating through safely.
One cave route leads to a green lake across complex terrain with significant elevation change. This underground route demands time and stamina but rewards explorers with an unusual destination found within the mountain.
