Trail guide
Greenough Lake Trail #103.1 is a brief out-and-back from the campground area to Greenough Lake. Plan about 0.4 miles round trip and roughly 20 minutes; the mapped trail corridor runs about 0.22 mile one way, and you return the same way. It is a quick lakeside stop with little climbing, not a longer workout.
Start at the campground-side end of Trail #103.1 and follow it toward the water. This is separate from the nearby Parkside Trail #103 and from a longer loop listed around the campground; those are different walks. The saved route ends near Greenough Lake and does not add an unverified campground loop.
The lake sits below forested Beartooth slopes and is used for canoeing, kayaking, and rainbow trout fishing. Those are lake activities, not extra miles on this trail. Aspen and pine grow around the campground, and bears, deer, and elk live in the area; wildlife sightings are never guaranteed.
