Living in Idaho with my Great Dane is an adventure every weekend. We hunt for spots where he can run free and be himself.
Idaho’s mountain trails are perfect—big, wild, and leash-free!
Ready for epic off-leash fun? Here are Idaho trails that welcome your giant pups to explore and play.
1. Moose Lake Loop (Idaho Panhandle National Forest)
The 4-mile loop circles an alpine lake where your furry friend can take refreshing dips between bursts of energy.
The wide trail offers plenty of space for larger dogs to maneuver without feeling constrained. Pine-scented air and occasional wildlife sightings (keep those recall commands sharp!) make this trail a sensory paradise for canines.
Pack extra water and treats—the elevation gain is moderate but steady.
2. Hell Roaring Lake Trail (Sawtooth Wilderness)
Don’t let the fiery name trick you! This trail offers heavenly experiences for large breeds who love to explore. The path winds through meadows bursting with wildflowers before reaching the spectacular alpine lake.
The 10-mile round trip journey provides ample exercise for energetic breeds. Remember that wilderness regulations apply here, though enforcement is minimal in this less-traveled area.
3. Fox Creek Loop (Sun Valley Area)
Fox Creek became our go-to trail when my pup was still mastering his recall skills.
The moderately challenging 5-mile loop offers dense forest sections where your dog can explore while staying within earshot. Seasonal streams create natural water stations throughout the hike.
My favorite feature is the varied terrain—from rocky outcroppings where your dog can practice agility to open meadows perfect for fetch breaks.
4. Corrals Trail #31 – Boise Ridge-To-Rivers
Who knew urban hiking could be so dog-friendly?
The Corrals Trail surprised us with its accessibility and dog-welcoming atmosphere. Just minutes from downtown Boise, this trail climbs steadily upward, rewarding effort with sweeping valley views.
The trail’s width accommodates even the most enthusiastic side-to-side bouncing that larger breeds often display. Bring poop bags as this trail sees heavy traffic.
5. Three Bears (Shane’s Loop) – Boise Ridge-To-Rivers
The name alone makes me smile!
The trail features just enough elevation change to work those large-breed muscles without exhaustion. What makes this trail special is its varied landscape.
One moment you’re in open hillsides with panoramic views, the next you’re navigating through cool forested sections that provide welcome shade.
I’ve noticed fewer bikers here than on other Ridge-to-Rivers trails, making it more relaxing for off-leash adventures.
6. Military Reserve Trails – Boise Foothills
The network of interconnected trails allows you to customize your adventure based on your dog’s energy level that day. The open landscape means you can always keep an eye on your four-legged explorer.
During spring, wildflowers carpet certain sections, creating magical settings for those Instagram-worthy dog photos. Fellow hikers here tend to be dog people themselves, making for positive social experiences.
Just watch for mountain bikers on some of the shared paths—I taught my pup to step aside when he hears bike bells, a skill that’s served us well throughout Idaho’s trail systems.
7. Eagle Island State Park Trails (Eagle)
While technically requiring leashes in some areas, the park offers designated off-leash sections where your big buddy can run free. The Boise River flows around this island park, creating natural boundaries and swimming opportunities for water-loving breeds.
The flat, well-maintained paths make this an excellent option for older large dogs or those recovering from injuries. We love coming here during weekdays when crowds thin out.
