In the summer, fishing, boating, camping and hiking are very popular at Half Moon Lake. Brown trout, brook trout, rainbows, whitefish and Mackinaw (lake trout) await the angler on this jewel of Wind River Mountain lakes. A National Forest boat launch and campground provide picnic tables, some trailer pull-throughs, vault toilets, fire grates, and refuse container. There is no drinking water. The campground is located in trees and willows adjacent to the lake. Water activities include canoeing, water skiing, personal water craft and inner tubing.

Beyond Half Moon Lake Resort, the Half Moon Lake Trailhead at the end of the dirt road is the starting point for a variety of hiking adventures, from an hour's stroll or day hike to strenuous backpacking into the high country. Adventurers may want to explore the inlet territory above the northeast corner of the lake, where Pole Creek spills down from Fayette Lake via a small waterfall. There is no bridge crossing this stream, so if you choose to cross be prepared to get wet or cross carefully on horseback. Several rugged trails give access to the high country and Bridger Wilderness; for more information contact the Pinedale Ranger District office.
