Excellent park and would come here again.
This is a great spot to go hiking if you are here on a long weekend and need to kill some time before heading out to wineries.
Parking is $6 for cars up to something like 8 people. Cards are accepted.
I only hiked here, but there are other facilities including RV camping, tent camping, dog run, mountain biking, and disc golf. Note that dogs are not welcome on trails but are okay in the camping sections of the park.
A full end to end hike of the park around the perimeter trails will take upwards of 5-6 hours.
The Western trails are a mixture of wooded and exposed trails. Eastern trials are really exposed and can be VERY steep in sections - I would attempt these only if you are in very good shape and have lots of water. Trails down the center of the park are a little more forgiving for those with children. Trails are probably not suitable for those with strollers.
Great views and would come here again if I'm in the area.
