No, haven’t tried Sierra Vista Open Space yet. I’ll have to add it to my destination list. I usually stay on the west side of the valley in the Santa Cruz mountains. Hiked Butano State Park last weekend and, after passing a few people and a Boy Scout troop in the first mile or so, had the next 4 miles completely to myself. Being deep in the redwoods all by yourself is amazing.
Me too.
Butano is great, and one of the least visited State Parks. Did you do a big loop?
Have you ever hiked Pescadero Creek County Park?
