At the eastern end of the town is the Leavenworth Ranger Station, built in 1936 and which now houses the Visitors Center. It was a Civilian Conservation Corps building project and on the National Register of Historic Places. Around 2002 more buildings were added to the property, which includes two additions to the original CCC building.

The Leavenworth Ski Hill Historic District contains intact examples of Rustic style architecture as well as the Pacific Northwest’s most intact example of a historic ski jump. Of the five known ski jumping facilities developed on Forest Service land in the Pacific Northwest Region, the Leavenworth Ski Hill was the best known and the only one known to have hosted national and international events. The district is also unique in the Pacific Northwest as one of the last CCC-built winter recreation facilities with an intact lodge as well as original adjunct buildings, a ski jump, and a functioning ski hill. In the first half of the 20th century, many of the winter sports areas developed on public lands had an associated outdoor club. Development of the Leavenworth Ski Hill started with the first annual Leavenworth Ski Jumping Classic, held in 1929 at a nearby slope. Interest from this tournament propelled the club to request a Forest Service special use permit to build and maintain two ski jumps, two toboggan runs, a parking area, a clubhouse, and a few associated outbuildings. The first ski jump within the historic district, a 50-meter Class B hill, opened in 1930. A few years later, the 90-meter wooden Class A jump was constructed; it was subsequently rebuilt in 1957. The buildings at the Leavenworth Ski Hill are part of the landscape and exhibit building materials typical of the region—wood shakes, logs, and fieldstone. The lodge’s (primarily) vertical log siding mimics the surrounding forest. Ornamentation is restrained and executed with natural materials, namely wood pole sunbursts in the gable ends.
