Sand Mountain Lookout Trail is a 4.6 mile out and back trail located near Harvard, Idaho that features a river. The trail is rated as moderate and primarily used for hiking.
It is a good hike, but there isn't really a peak. The trees clear near the "top" and give a good view of other slopes nearby. But then you go back into the trees and ends by connecting to another trail going either down or up away from the original trail. I chose to go up and it takes you alongside an ATV/motorbike path. I followed this new trail for 2 miles and got bored of it. (So there might be a peak, but after about 4.5/5 miles I turned back).
Simply breathtaking woods the moment you set foot on the trail. I didn't hike far since it took me quite a long time to find the trailhead. I will most certainly be returning to hike the full length and experience the spectacular views I expect to find at the peak.
