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.

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.

Highest point on Big Rock Ridge Fire Road with panoramic views of the Bay, Marin county, and even across the East bay to Mt. Diablo and south to San Francisco. A short spur trail here leads to a point with slightly better views down over Skywalker Ranch and the Lucas Valley.

A steep 400 meter (1300 feet) climb to the highest point in the park (426 m / 1407 ft), with views of the Seashore and Olema Valley. The loop passes through a mixed Douglas fir and oak forest and several open meadows. Start at the Bear Valley Trailhead and follow the Bear Valley Trail south for 0.3 km (0.2 mi.). Turn right on to the Mt. Wittenberg Trail and climb all the way to the top. https://www.nps.gov/pore/planyourvisit/hiking_guide.htm

Tucked next door to George Lucas's Skywalker Ranch, Lucas Valley Open Space protects 1,271 acres of verdant land and some of the season's most electrifying green hills. It's also home to the second highest point in Marin, reached via a 3.5-mile (one-way) hike. Big Rock Trail leads hikers and mountain bikers to its namesake ridge and a high point of 1,895 feet (an elevation second only to Mount Tam). There's no parking lot or visitor center signaling the trailhead, just a pull-off at the crest of Lucas Valley Road. Then it's onward (or, more like upward), weaving along singletrack that offers a bird's-eye view of Skywalker Ranch, along with seasonal flowers like blue-eyed grass, pink checkerbloom, and buttercups. The last half-mile is a ridge ramble with the high point marked by two antennas. The antennas aren't beautiful, but the views are, spanning from Mount St. Helena to Montara Mountain. The Tiburon Peninsula looks like a finger pointing into the Bay. From Hwy. 101 in Marin, exit Lucas Valley Rd and go about 5 miles west. The road crests at the "big rock." Keep going west and find a safe place to turn around, then park on the side of Lucas Valley Rd. Take Big Rock Trail heading north up to Big Rock Ridge. Elevation gains around 1200-1400ft Hike time 3-4 hours http://www.marincountyparks.org/Depts/PK/Divisions/Open-Space/Lucas-Valley
