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.

Upper Peters Dam Road is a well shaded path that partially navigates along Kent Lake shore. On the way out you can see the large dam looming overhead.

From the high ridge sweeping views open up to both sides, most still densely forested and often covered in morning mist that helps this forest survive despite the long periods without rain.

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.

This trail, part of the Pacific Coast Bike Trail (PCB), is a fantastic, mostly paved two-lane bike route that follows Lagunitas Creek under towering redwood forests and runs parallel to Sir Francis Drake Boulevard on the other side of the valley. It continues south from the campground all the way to the southern exit of the Park.

Big Rock Trail cuts through Lucas Valley Open Space to reach the 2nd highest point in Marin County. From later winter through early summer the hills are verdant green and often covered in wildflowers. Bring plenty of water and a wide brimmed hat if it's a warm day as there is little shade, but this means the views are wide open and beautiful.
