Osprey Falls

The Osprey Falls trail is considered challenging due to its significant elevation changes. Hikers will experience a strenuous descent of 700 to 800 feet into Sheepeater Canyon via steep and narrow switchbacks. The total round trip is typically 8 to 9.2 miles (12.8-14.5 km). Sturdy footwear is essential, and hikers should be prepared for a demanding journey.

Osprey Falls is located within Yellowstone National Park, so standard park entrance fees apply. There are no additional permits specifically required for hiking the Osprey Falls trail itself, beyond the park entrance fee.

The trailhead for Osprey Falls is located about 5 miles south of Mammoth Hot Springs on the Grand Loop Road. It is accessed via the Old Bunsen Peak Road. Parking is available at the trailhead, but it can fill up quickly, especially during peak season. Arriving early is often recommended.

Given the strenuous nature of the 8 to 9.2-mile round trip hike and the significant descent into Sheepeater Canyon, Osprey Falls is generally not recommended for families with young children or those seeking an easy outing. It is better suited for experienced hikers and older children who are accustomed to challenging trails.

No, pets are generally not allowed on trails in Yellowstone National Park, including the Osprey Falls trail. This policy is in place to protect wildlife and ensure visitor safety. Pets are permitted in developed areas, in vehicles on roads, and at campgrounds and picnic areas, but must be on a leash no longer than 6 feet.

The Osprey Falls area is rich in wildlife. Hikers frequently encounter elk, coyote, and mule deer. Given its location in Yellowstone, there is also a possibility of seeing grizzly bears. Visitors are advised to carry bear spray, make noise while hiking, and travel in groups to minimize encounters.

Osprey Falls plunges over ancient basalt cliffs formed by lava flows from the Osprey Basalt approximately 220,000 years ago. Sheepeater Canyon itself is notable for its impressive columnar basalt formations, which were exposed by the erosive action of the Gardner River. These features offer a dramatic backdrop to the waterfall.

The strenuous 8 to 9.2-mile (12.8-14.5 km) round trip hike to Osprey Falls typically takes 4 to 6 hours to complete, depending on individual fitness levels, pace, and time spent enjoying the falls and scenery.

Hikers should wear sturdy hiking boots with good ankle support due to the steep and uneven terrain. Layered clothing is recommended as weather conditions can change rapidly. Essential items include plenty of water, snacks, a map, navigation tools, sun protection, and bear spray. Binoculars can enhance wildlife viewing.

The primary route to Osprey Falls is an out-and-back trail that utilizes sections of the Old Bunsen Peak Road before descending into Sheepeater Canyon. While there isn't a direct loop trail to the falls, hikers can combine sections of the Old Bunsen Peak Road with other trails in the area for longer excursions, though reaching the falls typically involves the same descent and ascent.

Osprey Falls was named in 1885 by the Hague Survey, who observed numerous osprey birds hunting in the river canyon. Bunsen Peak, a prominent landmark along the trail, is named after Robert Wilhelm Eberhard von Bunsen, a 19th-century German chemist known for his studies of geothermal phenomena, connecting to Yellowstone's unique geological activity.
