Charlton Lake Trail is a 15.2 mile out and back trail located near La Pine, OR that features a lake and is rated as difficult. The trail is primarily used for mountain biking and is accessible from July until October.
We hiked the 6 mile section from The Twins trailhead north east to Charlton Lake. Quite a bit of elevation gain and loss until you end up at the lake, but there are some beautiful campsites right on the lake. The mosquitoes were almost no issue but the bees were quite active.
