Wild and Serpentine
by JimmyLyding

Pine Mountain is the highest point of a vast system of ridges in the heart of Marin County between Sir Francis Drake Blvd. to the north, the Bolinas-Fairfax Road to the east, and Hwy. 1 to the west. This hike is best enjoyed during the fall because the heat of summer would make the long stretches in the open unbearable and the rains of winter would turn the trail to mush. Indeed fall is my favorite time of year in the Bay Area. A lot of people would call it "Indian Summer" because the mornings are crisp and cool, afternoons are warm, and evenings cool off quickly. These wildlands that are protected by the Marin Municipal Watershed Mount Tamalpais District are one of the largest pieces of open space in Marin County.


The trailhead is across the Bolinas-Fairfax Road from a small parking area, and it immediately begins to gain elevation. The first section of the Pine Mountain Fire Road covers about a mile, and provides a good introduction to the serpentine geology that's common in the area. Serpentine is low in nutrients and high in heavy metals which means only a few plants can survive here. Here you see Sargent's cypress which is a small conifer that closely resembles a juniper. Most specimens only grow to about 10' or shorter out of the dense chaparral. The first mile and 400' of gain reach a junction that leads to Carson Falls 0.7 mile away, then a further half mile leads to a junction with the San Geronimo Ridge Road. These roads are fire roads which means there are no vehicles, but occasional mountain bikers. Go left to stay on the Pine Mountain Road to continue on to Pine Mountain.

Travel through a mix of chaparral and smallish Douglas firs as the dirt road gently winds up to the summit of Pine Mtn. The actual summit is nothing more than the highest point of a complex of ridges, and the views really open up as the route heads west near the top of a ridge heading north towards Kent Lake. There's a spur trail to the left/south a mile past the summit that leads to Poison Tank Spring.

Continue on Pine Mountain Fire Road as it drops down to about 400' above sea level and the forest closes in. The birches and tanoaks that replace the chaparral give way to redwoods and Douglas firs. You'll notice Kent Lake, a reservoir that supplies drinking water to the urban portion of Marin on the east side of the peninsula, a few hundred feet below to the north. The dirt road goes almost 5.5 miles as it winds along an arm of the lake before following Big Carson Creek, crossing it, and winding up to San Geronimo Fire Road on top of Big Carson Ridge. The bottom of the Big Carson drainage has second-growth redwoods (and bugs), then the chaparral reappears as the route travels higher.

It's about 9 miles to this point, but there are plenty of more steps ahead. Go right/east on the San Geronimo Fire Road all the way back to the Pine Mountain Fire Road after passing the Conifer Fire Road (1 mile), Bay Area Ridge Trail, then Cascade Canyon Road (dirt, primitive) 2.5 miles further. This area has similar vegetation to the beginning, but also has dense thickets of short Sargent's cypress. A half mile later leads to the Pine Mountain Fire Road, and continue another 1/3 mile to another junction before bombing downhill on the original trail that goes 400' and a mile down-up-down to the trailhead.

    From US Hwy 101 take the 3rd St. exit in San Rafael, CA. Go west on 3rd St. as it turns into Sir Francis Drake Blvd. Continue approx. 10 miles west to Fairfax. Go left on Pacheco St., then right on Mono before reaching the Bolinas-Fairfax Road 2 blocks to the west. Take the Bolinas road 2 miles to the Meadow Club Golf Course then another mile up (south) to the trailhead. There is a parking area on the south side of the road with room for about 2 dozen cars. The trailhead is on the other side of the road.
