Big Rock Ridge, a striking ridge near Novato, California, standing as Marin County's second-tallest peak. Spanning 5 miles from northwest to east, it creates a natural boundary for central and southern Marin County. Named after the rock at the base of Big Rock Trail, this ridge promises awe-inspiring views and invigorating trails.

The Lagunitas Dam, completed 151 years ago, was built in less than four months and was 480 feet long with a crest of 20 feet. The purpose was to supply development in the San Rafael area. Its current capacity is 350 acre-feet or 114 million gallons. Lake Lagunitas is one of seven Marin Municipal County Reservoirs, and the combined rainfall collected from these reservoirs makes up around 75 % of the district's water supply.

Don't be fooled, 'Alpine Lake' is the name of this body of water, but the fact that it is an alpine lake is highly debatably at a lowly 768 feet. Irregardless, the views are still nice. You can look but not touch as there is no swimming or boating allowed in the lake.

Steeped in local history involving hikers, bikers, and equestrians Bill's Trail is now open to all users. After breathing in the lush forest air you see why all three groups fought so hard to access this beautiful trail.

Along the trail you'll find redwoods, grasslands, and a nice viewpoint. This trail is pretty heavily trafficked and there is a lot of poison oak in the area.
