Julie & Keith B. on Bear Creek Redwoods Open Space Preserve
For the permit
Because you need to get a permit (easy), there won't be many (or any) other hikers. It's an interesting place, with an abandoned college and a couple of ponds. Stick with the area bounded by Bear Creek, 17, and the pond that is NOT at the entry/ trail head for the most interested hiking. Hilly but not too.
