Prospect Rock is a short, but steep, popular, family-friendly hike in the Lamoille Valley just north of Johnson, Vermont. One added benefit of this hike is that you travel along the famous Long Trail, a thru-hike that traverses the state of Vermont. This 2.6-mile round-trip hike begins by a short descent to a marsh before crossing a suspension bridge over the Lamoille River near Ithiel Falls before entering the woods. Once in the forest, you climb at a moderate grade until you hit a rock headwall. The trail begins to switchback steeply up the hillside before finally leveling off near the summit of Prospect Rock. From the flat bedrock overlook at the top, you get fantastic views of Lamoille River and the Sterling Range, making it a great spot to snap some photos and eat lunch.
