ColorFall Canyon
The hundreds of acres of open space surrounding Mount Tam are packed with surprises. Take Baltimore Canyon Open Space Preserve, a 193-acre gem on the eastern side of Tam. Here, an easy network of trails weaves through forests of Douglas fir, madrone, and second-growth redwoods, with punchy fall colors and views to boot. Start a 3.5-mile (round-trip) hike from Crown fire road where big-leaf maples are currently displaying leaves of light-green, deep yellow and burnt orange. Weave up and along the Mount Tam watershed on Hoo-Koo-E-Koo Trail (try saying that five times fast!). Connect to the Blithedale Ridge fire road where the vistas are best: Mount Tam towers from behind, while San Pablo Bay and Mill Valley swoop left to right. The views give way to a forest of second-growth redwoods, spawned from what were once some the largest redwoods in the Bay Area. Follow the Crown fire road back to the trailhead. Canyon-ball!From Hwy. 101 going north, exit Sir Francis Drake Blvd. Continue to the town of Kentfield and turn left onto College Ave. Take a right on Woodland Rd., then a left on Evergreen Rd. Take this up the mountain. Turn left on Crown Rd., drive to the end and park. Cross the gate found at the end of Crown Rd. Hike a few minutes and take your first right on the Hoo-Koo-E-Koo Trail. After a mile you'll reach Blithedale Ridge fire road; turn left. After .75-mile reach a four-way junction with a sign for "H Line fire road." Make a hairpin left turn here. In a few minutes you'll reach the Crown fire road (a.k.a., Southern Marin Line fire road). Turn left here and hike 1 mile back to the trailhead. Here's a map of Baltimore Canyon Open Space Preserve. Dog-friendly!
