The ideal time to hike this trail is typically from late summer into early fall. The initial crossing of Torrey Creek, which is unbridged, can be dangerously deep and fast-flowing until late summer. By then, water levels are usually lower, making the ford safer. Be prepared for rapidly changing alpine weather conditions at higher elevations.
No, the Old Glacier Trail is considered a difficult and strenuous hike, not suitable for beginners or young children. It involves significant elevation gain, reaching over 10,000 feet, and features a challenging, unbridged river crossing at the start. Hikers should have considerable experience and be prepared for rugged alpine terrain.
The trail begins south of the horse trailer parking area. Specific parking details for the Wind River Range access points should be researched locally before your trip, as conditions and regulations can change.
Yes, dogs are generally allowed on this trail within the Fitzpatrick Wilderness. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all trail users. Always practice Leave No Trace principles, including packing out all pet waste.
While there isn't typically an entrance fee for the Fitzpatrick Wilderness itself, permits may be required for overnight backpacking or for specific activities. It's crucial to check with the local Forest Service office (e.g., Shoshone National Forest) for the most current regulations regarding permits, especially for overnight stays or group sizes, before planning your trip.
The terrain is varied and challenging. It starts with a potentially hazardous, unbridged crossing of Torrey Creek. Beyond that, you'll encounter muddy and boggy sections, especially where horses frequently use the trail. As you ascend, the trail leads into rugged alpine environments with significant elevation gain, switchbacks, and potentially rocky sections.
As you gain elevation, the trail offers stunning views of Torrey Peak, Middle Mountain, Whiskey Mountain, and the Absaroka Range. You'll also get expansive vistas of Horse Ridge and Burro Flats. The meadows of Bomber Basin provide beautiful scenery, and higher elevations reveal vast alpine landscapes. You'll also pass by Double Lake.
The 'Old' Glacier Trail, as described here, includes a challenging and potentially dangerous unbridged crossing of Torrey Creek at its outset. The 'New' Glacier Trail was constructed after a landslide in 1976 to provide a safer alternative for hikers, bypassing this hazardous crossing. For most hikers, especially those without extensive river crossing experience, the 'New' Glacier Trail is the recommended and safer option. The 'Old' route is still used by outfitters.
Yes, the route also passes through sections of the Old Glacier Trail and the Glacier Trail.
Given the trail's difficulty and alpine environment, pack essentials include sturdy hiking boots, layers of clothing for rapidly changing weather, rain gear, plenty of water and food, a map and compass/GPS, a first-aid kit, and bear spray. Be prepared for potential river crossings, even in late summer. Sun protection and insect repellent are also highly recommended.
The Old Glacier Trail is located in a remote wilderness area. Amenities like restrooms, water sources, or visitor centers are very limited or non-existent directly at the trailhead. Plan to be self-sufficient and carry everything you need. Nearby towns may offer basic services, but expect a drive.
