Mallard Creek Ski Trail (U.S. National Park Service)

Views from the Mallard Creek Trail looking toward Midway Geyser Basin and the Madison Range.

The Mallard Creek Ski Trail is a 12 mile (19.3 km) round-trip, most-difficult, skier-tracked trail that takes advanced skiers over challenging terrain. This trail branches off the Mallard Lake Trail 0.2 miles (0.3 km) before the lake. From the junction, the trail climbs steeply up switchbacks to a ridge overlooking Mallard Lake and then heads northwest for approximately 4 miles (6.4 km). The trail has many challenging turns and crosses numerous deep gullies. Sections of the trail may be hard to follow and may not be well marked. Only advanced skiers should attempt this trail. The return to Old Faithful is another 4 miles (6.4 km) over gently rolling terrain along the Powerline Trail and through the Upper Geyser Basin.

Notes: CAUTION: recommended for advanced skiers only due to steep terrain. Bison and elk frequent this trail. Federal regulations require you to stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from bison and all other wild animals. Stay on boardwalks and designated ski trails. The ground is unstable in hydrothermal areas.
