Quartz Mountain Nature Park, Nature park and protected area near Lake Altus-Lugert, Oklahoma, United States

Quartz Mountain Nature Park covers 4,284 acres of land on the west side of Lake Altus-Lugert, at the western end of the Wichita Mountains, 13 miles east of Mangum. The park sits at about 475 metres above sea level, with mostly flat ground rising to granite hills; King Mountain, 730 metres high, stands 8.1 km to the south.

The park was developed in the 1930s during the Great Depression as one of Oklahoma's first protected areas. The Civilian Conservation Corps built the infrastructure and shaped the landscape into the park that exists today.

Since 1978 the park has hosted the Oklahoma Summer Arts Institute, where Oklahomans aged 14 to 18 audition to study with established artists. The $17 million Resort and Arts Conference Center opened on March 8, 2001, adding a performing arts complex to the lodge grounds.

The park offers camping, hiking trails, rock climbing, and boating on the lake for visitors of all skill levels. Check ahead to see which activities are available during your planned visit, as some are seasonal.

Baldy Point, on the park's west side, was a privately owned climbing destination from the 1970s. The Access Fund bought the land in 2001 and donated it to the State of Oklahoma, which is why the cliff stayed open to climbers.
