The Highline Recreational Trail is a 55-mile path that runs primarily through Idaho with a section that leads into northern Utah as well. This is the longest trail in the Caribou-Targhee and Cache National Forests, and most people access the trail from the Emigration Canyon Campground in Montpelier, Idaho. In addition to foot traffic, this trail is open to cross-country skiers, snowshoers, and equestrians, and it's dog-friendly!
Several other trails intersect the Highline Trail -- because of all the scenic spots to stop and check out along the way, most people just hike a section of the trail. If you'd like, you can hike the entire trail and stop to camp at one of several campsites in the national forests along the way. The Highline Trail is the best way to explore the Bear River Mountain Range that runs through southeastern Idaho and northeastern Utah. Whether you begin your trek by Soda Point in Idaho or Beaver Creek in Utah, you'll find there is little elevation gain (or loss) during your journey.
There are several points of interest along the Highline Trail, so be sure to plan your route so you don't miss any. One of the trail's highlights is the Minnetonka Cave. You'll find the cave about 32 miles into the hike in St. Charles Canyon. There are nine different rooms in this cave where you can explore stalactites, stalagmites, and travertine. Be sure to dress for chilly weather, because the cave is always at a chilly 40 degrees.
About 29 miles into your hike, you'll also come to Bloomington Lake, which is another scenic spot you won't want to miss. During the summer, visitors like to swim in this lake, so don't forget your swimsuit!
Visitors are asked to keep their dog on a leash on the Highline Trail and to clean up after them as they go -- be sure to bring lots of doggie bags. You and your pup will love exploring the mountains of Idaho and Utah on the Highline Trail together!
