Wenatchee National Forest, National Forest in central Washington, United States.

Wenatchee National Forest spans across the Cascade Range and contains multiple wilderness areas along with numerous alpine lakes and varied terrain. The landscape transitions from thick forests to open mountain peaks throughout the protected area.

The Chelan National Forest was created by the U.S. Forest Service on July 1, 1908, from 2,492,500 acres of the Washington National Forest and named after the city of Chelan, its headquarters. On July 1, 1911, part of it became the Okanogan National Forest; the whole was reunited in 1921, and the Okanogan name returned in 1955. The two forests were administratively combined in 2000 and took the name Okanogan–Wenatchee National Forest in 2007.

The forest lies in Chelan, Kittitas and Yakima counties, and its ranger districts are named for the towns where they are headquartered: Chelan, Cle Elum, Entiat, Naches, Leavenworth and Winthrop in the Methow Valley. The name Wenatchee comes from the river and city at its centre.

A network of ranger stations throughout the area provides current information about trail conditions and required permits for visitors. Spring through early fall offers the best access, as most routes remain free from snow during these months.

The largest alpine lake in the forest can only be reached by hiking or horseback, creating a remote experience for adventurous visitors. This isolation contrasts sharply with the more easily accessible areas elsewhere.
