DescriptionNice, steady climb on a fireroad popular with runners, hikers and mtn bikers alike. Many route possibilities with a mix of fireroads & single track accessible from this main road, including a popular route to Mt. Tam.

Start in the shade of a beautiful wooded canyon and climb toward the sunshine and Mt. Tam. Great views of Bay Area as you reach Summit Rd (approx. 2 miles). Continue on Fern Canyon (paved) for a short section, then access Old RR Grade again (dirt) to keep ascending toward Mt. Tam (another 4-6 miles). Make a ~7 mile loop by hopping on Hoo-Koo-E-Koo Fire Road off of RR Grade (approx 0.7 mi after paved section), then Blithedale Ridge to H-Line, which will take you back to Old RR Grade almost at the point the pin is dropped (this loop is up, rolling, then down).

Runners/hikers can also pick up Temelpa Tr. off of Fern Canyon if they want to switch to steep single-track.
