The north entrance to Crater Lake National Park closed Monday for firefighting operations related to the 4,885 acre-Spruce Lake Fire, burning west of the park.

Park visitors traveling from the north are being asked to continue south on U.S. Highway 97 to Route 422 at Chiloquin, then head to Route 62 to the south entrance of the park.

There are no entrance fees for drivers traveling Route 62 through the southern part of the park. Commercial trucks remain prohibited on Route 62 within the park.

Traffic delays are expected to increase at the Annie Creek entrance station since all park traffic will be routed through the station during the temporary closure of the north entrance, according to the park.

All other roads within the park and all facilities remain open.

The Pacific Crest Trail is also temporarily closed from North Entrance Road to the park’s north boundary. In addition, the Rim Trail has been closed for the second time this summer, and West Rim Drive continues to be closed from 9 p.m. Sunday through 4 p.m. Friday.
