This is a great after-work hike if you live nearby, or a mild weekend hike if you only have a couple of hours. You’ll find nice open areas with views of the mountains and a bit of ponderosa pine forest on the Spring Brook portion as well. These trails are very popular with mountain bikers, so be careful when coming around the bends.
