“A moderate run along the ridge of Rattlesnake Mountain with great views of the Cascades.”— Eric Ashley
From there, the trail continues switchbacking along the ridge. Occasionally, the route will make use of old roadways, but thorough signage makes the navigating straightforward. Just over four miles in, the trail comes to Grand Prospect Viewpoint. Take a moment to rest on the conveniently placed benches as you soak in the sights. If running as an out-and-back, this is a good turn around spot.
The climbing isn't done, but the going remains easy over the next few miles as the trail follows the rolling elevation of the ridge. The last few miles of the trail descends along a series of switchbacks through a young forest. The big highlights will be three ledges that provide great views. The lowest is Rattlesnake Ledge and it's a very popular destination, so expect lots of company here and as you continue down the trail to where it ends on a service road near Rattlesnake Lake.
