The chalet is reached only by trail, via hiking or horseback. One of the two trails leading to the chalet are 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, so it is important to plan ahead.
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 has been added, but is not part of the historic landmark designation. The dormitory building, completed in 1913, is built with random rubble masonry, providing a feel of architectural ruggedness, and is topped with a large gable roof that has two dormers on either side. The kitchen building, completed in 1912, is also made of random rubble masonry, but uses 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 provides traditional meal service: dinner, breakfast, and either a trail lunch or an ala carte lunch in the dining room. The guest rooms are private, but in line with the backcountry experience, there is no electricity or heat. There is running water at the bathroom facility.
