Barnabe Fire Road starts from the midsection of the Cross Marin
trail and can be ridden in either direction. Begin by heading up a steep hillside to gain the ridge. The grade eases but remains even as the trail ducks in and out of forested areas and grassy fields.
If you've made it this far, it would be a shame not to take in the stupendous views from Barnabe Peak, so it is highly recommended that you visit Barnabe Peak's summit via the short out-and-back towards the radio and fire observation towers. From the summit, you'll marvel at the panorama that includes views of Mount Tamalpais, Bolinas Ridge
, Mt. Diablo, Lagunitas, Tomales Bay, and Point Reyes. In case you're curious, Barnabe Peak is named after (the explorer) John Fremont's mule who, once he was retired, frequently escaped from Samuel P. Taylor's farm to ramble this area.
When you're finished admiring the views, roll back down the ridge on Barnabe Fire Road (sometimes labeled "Riding and Hiking Trail"). Ride past the junction with Bill's Trail
(hiking only) and continue steeply downhill, pausing when needed to rest your hands! The trail moves steadily through open, nondescript fields scattered with coyote brush, but watch for wildflowers in the spring. Barnabe Fire Road ends at the junction with Gravesite Road
