The two open space preserves meet in this valley of stately redwood trees that's refreshingly cool even in summer, which is welcome before or after the climbs that go both directions in and out of this valley.

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.
