Bohinj Tunnel

The Bohinj Tunnel is a railway passage stretching about 6.3 km through mountainous terrain. It links the Julian Alps region with a major transport network heading toward the Adriatic coast.

The tunnel was completed in 1906 during the Austro-Hungarian period and served as a crucial link between Central Europe and the port of Trieste. Its construction marked an important milestone for regional rail connections.

The tunnel is a registered cultural heritage site in Slovenia, showcasing early engineering from the 1900s. The stone construction reflects the craftsmanship and methods that workers used to build such ambitious projects at that time.

For visitors, train services between Jesenice and Nova Gorica via the Bohinj railway line offer a practical way to experience the tunnel firsthand. Traveling through the mountain passage provides direct insight into this engineering feat.

At about 6.3 km, this is the longest railway tunnel in the country. The original stone portals at both entrances date from when it was completed and look like gateways to a past era.
