The Bridger Ridge Traverse is considered a difficult and physically demanding hike. It's often described as 'burly and technical,' featuring significant elevation changes, steep climbs, and narrow sections along the ridgeline. Hikers should be prepared for mixed terrain, including rocky areas and scree fields, with considerable exposure to the elements above the timberline.
The most common route for the Bridger Ridge Traverse is point-to-point, typically starting from Fairy Lake Trailhead and ending at the College 'M' Trailhead, or vice versa. Parking is available at both locations, but it's important to note that this is not a loop, so arranging transportation or a shuttle between the trailheads is necessary.
The Bridger Ridge Traverse is located within the Custer Gallatin National Forest. Generally, there are no specific hiking permits required for day use on this trail, nor are there entrance fees for the National Forest itself. However, always check the latest regulations with the Custer Gallatin National Forest before your trip, as rules can change.
The best time to hike the Bridger Ridge Traverse is typically during the summer months, from late June through early September, when the snow has melted and weather conditions are generally more stable. An early start is recommended due to the length and exposure of the trail.
While dogs are generally allowed on trails within the Custer Gallatin National Forest, the Bridger Ridge Traverse is a very challenging and exposed route. Consider your dog's endurance and paw protection for rocky terrain. Always keep dogs on a leash and be prepared for potential wildlife encounters, especially with grizzly bears in the area.
Water sources are scarce along the Bridger Ridge Traverse, especially once you are on the ridge above the timberline. Hikers should carry all the water they will need for the entire duration of this long and exposed hike. Plan for at least 3-4 liters per person.
The traverse offers expansive 360-degree views for most of its length, including the Gallatin Valley and the Crazy Mountains. You'll pass several prominent peaks such as Sacagawea Peak, Nya Nuki Peak, Saddle Peak, Bridger Peak, and Baldy Mountain Summit. Other notable points include View of Bridger Pass and The "M" Overlook.
The Bridger Mountains are home to various wildlife. Hikers frequently spot mountain goats, especially around Sacagawea Peak. The area is also grizzly bear territory, so it's crucial to carry bear spray and know how to use it, make noise, and store food properly.
Given that the Bridger Ridge Traverse is a point-to-point hike, shuttle services are often utilized by hikers to connect the starting and ending trailheads. While not officially provided by the forest service, local outfitters or private arrangements are common. It's advisable to research and book these services in advance.
Yes, the route for the Bridger Ridge Traverse utilizes sections of several trails. You will find yourself on parts of the Bridger Ridge, Bridger Foothills Trail, Bridger Ridge Trail, Ridge Trail, Fairy Lake Access Trail, Sacagawea Pass, College 'M' Steep Trail, Ross Pass Trail, and College 'M' Popular Trail.
The full Bridger Ridge Traverse is not considered family-friendly due to its extreme length, difficulty, and exposure. However, shorter, less strenuous hikes can be accessed from the same trailheads. For example, a hike to Fairy Lake or a shorter ascent to Sacagawea Peak from Fairy Lake Trailhead, or a hike up to The "M" Overlook from the College 'M' Trailhead, offer a taste of the Bridger Mountains without committing to the full traverse.
For this challenging traverse, essential gear includes plenty of water (at least 3-4 liters), high-energy food, sun protection (hat, sunglasses, sunscreen), layers of clothing for varying weather, a headlamp, a first-aid kit, navigation tools (map, compass, GPS), and bear spray. Sturdy hiking boots with good ankle support are also crucial for the technical terrain.
