Most of the park is hiking trails only, but there’s an old logging trail that is open to horses and bicycles. From the entrance to the park, it runs about 5 miles, through some hilly but not overwhelming terrain.
It’s a very pretty ride, but I’m partial to redwood forests.
There are a number of hiking trails, including on that leads to Tiptoe Falls, a small but charming waterfall surrounded by ferns; we meant to go find it, but took the wrong trail, and never got there.
Even if you don’t see the falls, though, it’s a good ride.
