The Grass Lake Trail connects the Long Lake Trail and Gray Eagle Creek Trail with the Bear Lakes Loop. It features a nice waterfall at the northern end. The waterfall is on the other side of the trail and worth seeing. From the intersection with Gray Eagle Creek Trail and Long Lake Trail, head south on the Grass Lake Trail, which will eventually take you past Grass Lake on the right and to a campground and trailhead soon after. Keep right through the campground, and you'll see a path heading out of the campground towards the Bear Lakes Loop. This path will intersect the northeastern part of the Bear Lakes Loop.
