Grotta della Bigonda

Grotta della Bigonda is an extensive cave system in Valsugana composed of three distinct levels within dolomite rock formations. The passages span across multiple vertical sections and display varied geological structures throughout their development.

The cave system was discovered in 1952 during aqueduct construction work near Ospedaletto and subsequently explored by local mountaineering groups. These early expeditions established the foundation for understanding this underground network.

This cave system holds significance for the region's natural heritage and draws researchers who study its underground formations and geological importance. Local communities view it as a window into Trentino's hidden landscapes beneath the surface.

Access to the site is from Ospedaletto, with guided visits available primarily during winter months when water levels are lower. Visitors should bring warm clothing and sturdy footwear as the underground environment is cool and can be slippery.

The cave system harbors specialized animal species found nowhere else, having adapted to the particular underground conditions of this isolated environment. This rare ecosystem offers insights into how life survives in the darkness below the surface.
