Rheinfels Castle Tunnels

A long network of tunnels run under the Rheinsfels Castle in the Rhine River Valley.

These interesting tunnels from the 14th century are open to the public and are fascinating to explore.

As some of tunnels are unlit, it is a good idea to bring along a flashlight.

Tourists should be careful not to hit their heads on the ceilings as the Rheinfels tunnels were definitely not designed for tall people!
