It's very pretty, and once past the small lake, very private. Our dog had a blast.
This is NOT an easy hike. The trail is rougher and quite a bit longer than the Trail Guide states. It took us a little over 4 hours to complete the Red Trail and that's without the recommended White Trail side trip.
Once past the lake, there are no obvious paths, so you need to rely on the trail markers.
Expect to do a lot of scrambling because the trails are poorly maintained, heavily overgrown and many trail markers are missing.
There are a couple of spots where you have to be very careful crossing streams, (including one derelict bridge).
One more note about the driving directions. When you turn on to Jonestown Road, the entrance to the park is about 150 feet on the left. It's a gravel road that's easy to miss.
