Tunk Mountain is a mid-elevation peak located in Okanogan County, Washington. The peak is most famous for its fire lookout tower which still exists today. In addition, the mountain is important to peakbaggers due to its status as one of the most prominent peaks in Washington. With 2013' of clean prominence, Tunk Mountain is the 140th-most prominent peak in Washington, one of only 144 peaks with at least 2000' of clean prominence.

The summit originally had a lookout tower built during 1933 by the United States Forest Service, but its primary purpose was as a detection point rather than a fire lookout. The original lookout tower was a 40' tall pole tower with L-4 cab. The U.S. Forest Service later transferred ownership of the tower to the State of Washington. During 1966, the Washington Department of Natural Resources (DNR) destroyed the original lookout tower. The organization replaced it with another 40' tall tower but with a live-in cab included. After many years the lookout tower was no longer officially used by DNR, and the organization sold the tower to private ownership during the mid-1990s. The private group has a special use permit allowing the tower to remain on-site, and volunteers maintain the structure. The Tunk Mountain lookout tower is listed on the National Historic Lookout Register.

Despite private ownership of the lookout tower, and despite the tower being locked-up as a result, the summit area is still accessible to the public. A road system leads all the way to the summit, and currently the road system is usable by any street-legal vehicle. Due to having a vast prominent vantage point and being easily accessible, the summit area has been an ideal location for several small communications towers. The United States Geological Survey (USGS) placed a benchmark disk at the summit during 1936, and that matel disk is still located there.

The Tunk Mountain summit is open and accessible to the public, year-round. The peak is a simple drive-up during snow-free periods, and would be a nice snowshoe trek during snow-cover.

NOTE: Northwest of the peak along Highway 20 is a sign pointing up an old road (Talkire Lake Road?) referencing the "Tunk Mountain Lookout". It is possible that road might eventually lead to the correct location and seem like a more-direct route, but the road conditions and public accessibility are currently unknown. Please use the driving directions listed in the "Getting There" section above, until further notice.


Camping in the lookout tower might be possible through the private ownership group. Please see the "Red Tape" section above for details.
