Best appreciated after winter rainfall, this waterfall is right along Old White Hill Grade trail. If surprised by a shower the massive pipe channeling the usually small trickle of water under the trail can serve as an emergency roof, but be careful if water levels increase suddenly ...

Bay Area Ridge Trailhead

Highlight • Trail

There is plenty of street parking at this trailhead, with the amazing Big Rock nearby to make it easy to spot. The Bay Area Ridge Trail runs along the ridgelines surrounding the San Francisco Bay area and spans over 500 miles of multi-use trails. This portion offers some of the best views of Marin and the city skyline.

Upper Big Rock Trail

Highlight (Segment) • Trail

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.

Big Rock Ridge

Highlight (Segment) • Summit

With 360 degree panoramas at multiple points, perfectly groomed trails, and undulations to keep things interesting (and challenging) this is a great ridge to enjoy for multiple abilities.
