Dog-friendly Two Top Snowmobile Trail is located inside the Custer Gallatin National Forest adjacent to Yellowstone National Park. One of the area's most popular snowmobile trails, it is accessible directly from the town of West Yellowstone, and straddles the Continental Divide, making it one of the highest viewpoints in the area. Open from December 1 through April 15 for snowmobiling, cross-country skiing and snowshoeing, the trail welcomes leashed doggos any time of year for hiking and camping with their humans. Remnants of winter snows remain on the mountain into June and July, and you may be surprised to see "snow ghosts," sculptures formed by snow and ice settling on trees in lumpy, rounded, almost ghoulish shapes.
The snowmobile trail is well-marked and groomed, but there is plenty of opportunity to find some off-trail fun in the woods or some of the snow bowls in the valleys between ridges. When there's no snow, the markings remain and guide you through the deeply forested back country where you'll encounter birds like eagles and songbirds, antelope, moose and small mammals like squirrels that forage in the undergrowth. At the base of the mountain and above the treeline, you'll be surrounded by wildflowers in the spring while hiking through grassy meadows, such as buttercup, figwort, wild lily, wild roses and sunflowers.
At the summit of Mount Two Top, you can turn in all directions to view the Teton Mountain Range to the south, Yellowstone to the east, and Idaho's Centennial Mountains just across the state line. While this is a challenging climb, hiking the Two Top Trail is well worth the effort for its furtastic panoramas.
Whether you're wanting to visit Two Top Snowmobile Trail in summer or winter, you and your fur-pup are in for a treat. Summer or winter camping await, along with miles and miles of trails that meander through the forest and to the summit!
