Been there twice. If you take the Mission Creek Preserve entrance, you'll connect with the southern PCT trail intersection. Take the south fork and climb up the trail to a ridge on the trail that gives a view of Whitewater Canyon and the trail down the mountain towards the Whitewater River. The hike is close to 1000 ft elevation change. The view is spectacular. Take plenty of water as this is close to 8 miles from Mission Creek Preserve Road entrance. There is the stone house with picnic tables and even. Separate bathrooms. Along the way you'll see a massive growth of wild grapes in and around tall trees. Great views there as well. The rock formations are fascinating for the geologically inclined. Saw some rabbits, and heard lots of birds, but didn't see any other wild life (thank goodness no snakes!)
