Sperry Chalet was located about seven miles east of Lake McDonald in Glacier National Park in the U.S. state of Montana. The chalet was opened in 1914 by the Great Northern Railway and was a National Historic Landmark contributing property, being one of five structures in the Great Northern Railway Buildings National Historic Landmark. Along with Granite Park Chalet, Sperry Chalet is one of the two remaining backcountry chalets in Glacier National Park, both operated by Belton Chalets, Inc.
The chalet is reached only by trail, via hiking or horseback. One of the two trails leading to the chalet is the Sperry Trail, which starts at the Lake McDonald Lodge parking lot and stretches 6.7 miles to the chalet, climbing 3200 feet in the process. The trail passes along the base of Mount Brown and over the west ridge of Mount Edwards, with views of U-shaped valleys along the way. A side trip to Sperry Glacier is also possible, being a 4-mile hike (8 miles round trip). The other means of accessing the chalet is via the Gunsight Trail, which is a 12.1-mile hike from the Jackson Glacier Overlook on Going-to-the-Sun Road. This hike averages 9 hours.
The chalet, nestled in a glacial cirque, consists of two buildings from the Great Northern era: a two-story hotel building and a kitchen/dining room building. A restroom facility was added, but was not part of the historic landmark designation. The dormitory building, completed in 1913, was built with random rubble masonry, providing a feel of architectural ruggedness, and was topped with a large gable roof that had two dormers on either side. The kitchen building, completed in 1912, is also made of random rubble masonry, but used smaller stones and appears less striking in its design. The kitchen building is topped with a lower gable roof.
Unlike Granite Park Chalet, Sperry Chalet provided traditional meal service: dinner, breakfast, and either a trail lunch or an ala carte lunch in the dining room. The guest rooms were private, but in line with the backcountry experience, there was no electricity or heat. There is running water at the restroom facility.
On August 31, 2017 the hotel/dormitory building of Sperry Chalet burned during the Sprague Fire of 2017. The wood portions of the main chalet burned, gutting the structure, but the surrounding outbuildings were saved. After the fire, U.S. Secretary of the Interior Ryan Zinke stated that rebuilding the Sperry Chalet would be a top priority and an engineering firm had already inspected the structure and was preparing a proposal on how to reinforce the stone walls for the upcoming winter and other stabilization efforts. A fund for stabilization was established, overseen by the Glacier National Park Conservancy. Work to brace the stone walls to prevent their collapse was scheduled to begin in October 2017, with supplies brought in by helicopter.
