This walk will take us from Lucas Valley to the 1,895 foot summit of Big Rock Ridge, the second highest peak in the county after Mount Tamalpais. This walk involves a 1,200 ft elevation gain, but it doesn’t involve any particularly steep sections as it climbs through open grassland, oak woodland, and chaparral. The views along the way are excellent, and the panorama we’ll see from the summit is absolutely breathtaking. The total distance is a bit over 7 miles. Remember to bring enough water and food. This walk is for ages 15 and up. We request that no pets (except service animals) attend. Rain may cancel. If questionable weather, call (415) 893-9527 after 8am on the morning of the event to hear a recorded message if cancelled. Questions: Contact David Herlocker at DHerlocker@marincounty.org or (415) 893-9508. Meet at the Big Rock trailhead in San Rafael. DIRECTIONS: From Hwy 101 in San Rafael, take the exit for Lucas Valley Rd west approximately 5.5 miles (look for the big rock). The trailhead is on the north side of Lucas Valley Rd.
