The Mullan Loop is an easy half-mile interpretive trail showcasing parts of the old Mullan wagon road, built in the 1860s to connect Fort Benton with Fort Walla Walla, and newer Highway 10, built in 1916.
The Eagle Hut Loop is part of Fourth of July Pass’s winter recreation area. The 8.5-mile loop leads along both groomed and ungroomed trails and culminates at a back-country warming hut. The A-frame, built by Ian Truscott in 2007 as an Eagle Scout project, comes complete with benches and a small wood-fired stove.
Jeanette’ Jaunt is an excellent showshoe trail for beginners, following an old logging road along the side of a mountain paralleling I-90. For most of the trail the incline is negligible, signage is superb, trail maintenance is much improved, and heavy usage turns much of the trail into easily-traversed packed snow.
At just over 3000 feet altitude, snow-sufficiency can be hit or miss at the Fourth of July Recreation area. When there’s enough, this is a convenient and popular cross-country skiing and snowshoeing area, located just minutes from I-90. The trail system south of the freeway is entirely reserved for non-motorized recreation, and some of the trails are groomed for tracked cross-country skiing.
The Killarney Mountain trail isn’t much of a hike during summer months, since most of the route follows well-established forest service roads. During the winter months, however, the area south of the freeway is off-limits to motorized traffic, resulting in an snowshoe trek par excellence!
