Overview

North fire road on Loma AltaNorth road up Loma Alta
Marin County Open Space is a great getaway from the metropolitan Bay Area hubbub into the beautiful hills and wetlands north of San Francisco.
Loma Alta is a massive grass covered rolling hill with ranch lands centrally located in northern Marin County that has Open Space approaches from the north and south. This big old hill commands outstanding 360 views of the county and North Bay .






Easy fire roads gradually ascend in just a few miles to this often windswept summit. There are great views of the north flank of Mt. Tamalpais to the south. To the west is Barnabe Mountain, Nicasio Reservoir and the hills of northwestern Marin. Directly north is Big Rick Ridge rising above Lucas Valley and to the east is the vast expanse of the northern Bay Area will Mt. Diablo and the East Bay Hills. The SF skyline also rises off in the distance to the southeast.

Take the fire road on the right at the end of the bridge. This road drops down a bit. At .2 miles take the fire road that goes up to the left and follow it up about 3/4 mile to a junction. Go left on that fire road .9 miles as it switchbacks up to the south ridge of Loma Alta and follow it to the right on up to the top.
From Lucas Valley Road: From Hwy. 101 In Terra Linda go west on the Lucas Valley Road Exit and drive 6.3 miles through the valley then up to the pass at the big rock. Parking is on the south side.
