Sullivan Lake is a 7.2 mile out and back trail located near Metaline Falls, WA. The trail is primarily used for birding and is accessible from June until November.
Sullivan Lake is my favorite place to camp in this area. Last summer we finally did this hike. Great easy hike. Absolutely gorgeous! We had three dogs with us, who loved this hike just as much as us. Will definitely hike again!
We camped on Lake Sullivan and hiked the trail while we were there. It was a pretty easy trail. We saw big horn sheep running up and down the trail several times a day to get water. It was beautiful there and we boated on the intimate lake.
