Lake of the Isle

Trail Description

Lake of the Isle ascends up an old logging road. The trail appears to have been obstructed in various ways to prevent motor vehicles from passing through. For the first few miles, the hike travels through some rather dry and open forests. Mountains can be seen in the distance making it an exciting site. You’ll reach an intersection with a sign that will point you to either Twin Lakes or Four Mile Basin Lake. You make a left towards Twin Lakes over a bridge and into some denser forests. After another mile or so the trail takes a surprising dip into a very lush and dense forest over a creek. Shortly after this, you arrive at the first Twin Lake. Take a left crossing the creek/log dam and there is an obvious trail that picks up elevation quickly. You’ll hike through some denser lush forests for a little less than a mile before reaching an unnamed body of water. After this, the forest goes back to being fairly open. The trail then dips down into a swampy area, we had trouble following the trail between from what seemed like newer trail diversions and the swampy ground. Using our GPS we found our way across and once on the other side the trail was distinguishable again (we always recommend carrying a GPS!). You’ll gain a bit more elevation after this and after a half mile or so you’ll reach Lake of the Isle. We enjoyed a day of solitude with no one else on the trails!
