Drive Through the Historic Gilman Tunnels

When you can’t go over or around a mountain, simply drive right through it.  Right at the Guadalupe Box, you can experience driving through solid granite rock at the Gilman Tunnels in Jemez Springs.

Gilman Tunnels in Jemez Springs

Also known as the Jemez Tunnels, the channel was formerly used in the mid 1920s for about two decades to transport logs from the Jemez Mountains using the Santa Fe Northwestern Railway.

Upon the discontinuation of the Santa Fe Northwestern Railway, the tunnels were converted into what is now Forest Road 376.

While on your way to Soda Dam, Battleship Rock or Jemez Falls, the Gilman Tunnels should make your must-see list.
