Knowing where you can legally bring your dog matters more than reviews suggest. National parks ban dogs from most trails outright; national forests and state parks vary by location. We filtered the 6,169 mapped Montana trails to only those where the trail's data explicitly allows dogs (leashed or otherwise), then ranked by length and difficulty to surface the routes most dogs and most owners will enjoy. Always carry a leash, water, and waste bags — and check the trailhead sign for current rules.
Montana ranges from the Northern Rockies' glacier-carved peaks (Glacier NP, Bob Marshall Wilderness) to the rolling Great Plains east of the divide. Glacier's Avalanche Lake and Hidden Lake Overlook, Yellowstone's northern range (in Montana), and the Beartooth Highway pullouts deliver scenic, manageable introductions. Dog access in the US varies by land manager: federal national parks usually restrict dogs to paved areas, while national forests, BLM lands, and many state parks welcome leashed dogs on trail.
Our rankings here are data-driven — pulled from the 6,169 mapped entries OutsideAtlas tracks in Montana — but the data has limits worth being honest about. We surface trails where the OpenStreetMap `dog` tag is explicitly set to yes, leashed, or permissive. Many genuinely dog-friendly trails are missing this tag and won't appear; conversely, leash rules can change seasonally with wildlife management. Always verify at the trailhead.

A few pieces of context are worth keeping in mind specifically for Montana. Late June through mid-September is the high-country window; afternoon thunderstorms and grizzly activity are routine. Grizzly bears (carry spray, know how to use it), unbridged stream crossings, and lightning on exposed ridges are the recurring concerns.
Always cross-reference the official land-manager page before driving out — closures, fire restrictions, and seasonal road access can change quickly. Our trail pages link directly back to the OpenStreetMap source so you can see the tags we're working from.
If you're new to hiking generally, our beginner's guide covers footwear, layering, and the day-pack basics. For safety planning on bigger objectives, the ten essentials guide is worth twenty minutes of reading.
