The Piusa Sandstone Caves in Võru County are an extensive network of man-made galleries created during the mining of glass sand between 1922 and 1966. The total length of the underground passages exceeds 10 kilometers, with some vaulted ceilings reaching heights of up to six meters. Following the cessation of industrial activity, the caves became a critical sanctuary for hibernating bats, hosting Northern Europe's largest known colony with over 500 individuals from seven different species. The Piusa Visitor Centre provides controlled access to a viewing gallery, ensuring the protection of the delicate ecosystem and the safety of tourists. The surrounding landscape features distinct sandstone outcrops and pine forests, characteristic of the Devonian sandstone deposits in southern Estonia. The caves serve as a unique monument to Estonian industrial history and environmental conservation.

📋 Practical info
Getting there
The Piusa Sandstone Caves are situated in the far southeast of the country and are highly accessible via the regional road network.
Best season
Because the caves serve as a crucially important wintering habitat for bats, many areas are strictly closed off from autumn to late spring.
Terrain & paths
The surrounding terrain near the caves and visitor center is largely flat, excellently developed, and fully walkable for all visitors.
What to bring
Completely basic casual shoes are totally sufficient for walking around the complex, as the designated paths are highly manicured and firm.
Parking
At the visitor center, there is an incredibly massive, official parking lot providing more than ample space for both cars and tourist coaches.
Safety
The sandstone is intensely porous and exceptionally prone to collapse, making entirely unauthorized entry into unsecured cave passages strictly prohibited and life-threatening.
Time needed
A typical visit, encompassing a tour through the remarkably modern information center and a complete walk to the secured cave viewing points, requires roughly one to two solid hours.
