I needed a little conditioning hike for the old creaky knee, so we picked this one with some uphill, downhill, decent scenery and close to home. The trails are all in good shape, but somewhat overgrown in spots with those nasty invasive Himalayan blackberries. This is a trail system that is full of surprises, you never quite know where you are. There is signage at a few major intersections, but there are trails that just show up and don't appear on the map. The main trails are easy to follow, Main Trail, Pipeline, and Quarry. If you want to get down to the river, go down the River trail, the others don't have good access. Just stick to the main trails if you have no time for exploring. As many have said before, this park could use better signage and a better downloadable map. We saw very few people.
