I am only able to speak about the Redwood hike and not any of the other features of this park

Parking $5 I believe
Trail- dirt path that is pretty flat and it was an easy 2.5 mile hike or so
Destination- grove of Redwoods...cool to see in So Cal but they are smaller and on the dry side...worth coming to see but not eager to return
*suitable for young children and a quick, easy adventure for the family
