|Pinnacles National Monument|
While in the San Fransico area, I visited the Pinnacles National Monument. To be honest, I didn't expect too much but it ended up being one of my all time favorite national park experiences.
We took a 6+ mile trail that went through the heart of the pinnacles and the trail was incredible. It goes right through the rock cliffs and the trail actually has a good deal of exposure. It does have hand rails in that area (it's a national park after all) but it was really cool.
