From UT Hwy 44, turn south on the scenic Spirit Lake Scenic Backway (USFS road #001). This turnoff is located in the wide open sagebrush flats of Dowd Mountain, about 10 miles south of Manila. Follow the backway to its end, about 25 miles of mostly graded dirt road, right up against the spine of the high Uintas. Here you will find lovely Spirit Lake. Continue past the campground and look for the trailhead on your left. Follow the well marked trail into the forest and meadows - keep an eye out for moose in any of the brushy open areas. The trail splits in about 1 mile, but both directions end up at Tamarack lake (the left-hand fork goes past Jessen Lake as well).
