You'll have fun crawling boulders and roaming around high plateaus with some beautiful glacier lakes. Fishing is amazing and you can find great camping in the area. The High Lakes Trail is part of the OHV area of the same name, and is open to green-sticker vehicles. Stay on the designated trails.
This area, known as the Kimshew Mining District, has a long history starting with prospecting in the mid 1800s and continuing as late as 1980 with modern hydraulic mining. Source: Friends of the High Lakes, www.friendsofhighlakes.com.
