Going north on NM Highway 4, turn west on NM485, crossing the Jemez River, then through the small towns of Cañon and Gilman following the Guadalupe River. You are surrounded by striking mesas. Drive along the Rio Guadalupe's cascades to the Gilman Tunnels. Then climb through some of the oldest rocks in the Jemez Mountains as the canyon narrows at the Guadalupe Box.

The Gilman tunnels were originally blasted out of the rock in the 1920's for a logging railroad and are quite high. There are several spectacular turnouts on the short climb.

Logging ruins can still be found above the road on Peggy Mesa. There are great views of the Guadalupita and Virgin mesas.

Just past the tunnels the pavement ends. Follow the dirt forest road FR376 to the paved NM126, then back around to Highway 4.
