Szklary Tunnel

Szklary Tunnel is a railway passage in Szklary, Rzeszów County, extending 602 meters through the landscape. This makes it the longest narrow-gauge railway tunnel on the European continent.

The passage opened in September 1904 to carry sugar beets and timber through the region. This development supported industrial growth across the Podkarpacie area at that time.

This passage runs as part of the Pogorzanin narrow-gauge railway, a route that winds through the Mleczka River valley connecting Przeworsk and Dynow. Locals and visitors recognize it as a key landmark along this historic rail corridor.

This tunnel is currently closed to train traffic due to damage from recent floods and resulting landslides along the tracks. Visitors should be aware of access restrictions when planning a visit to the site.

During winter months, ice formations develop inside the tunnel, creating natural sculptures that attract photographers across the continent. This seasonal appearance makes it a special destination for those interested in natural displays.
