The St. Andrews Patrol Cabin was built by the National Park Service in 1922 as part of a network of stations near the boundaries of Mount Rainier National Park for rangers on patrol.

The one-room log structure stands along St. Andrews Creek and St. Andrews Creek Trail near the Westside Road and the western boundary of the national park.

The exterior of the cabin features a porch to the front.

The interior is finished with varnished logs and tongue and groove flooring.
