Dog Mountain, Mountain peak in Skamania County, Washington, United States

Dog Mountain is a peak in the Cascade Range located in the Columbia River Gorge in Washington. The mountain is accessed via a marked trail that passes through forests and open meadows, with different routes offering varying degrees of difficulty for hikers.

A fire lookout was built on the summit in 1931 and rebuilt in 1952 to watch for fires in Oregon's Mount Hood National Forest across the Columbia River. It was dismantled in 1967 after roads and airplanes made it obsolete. A hiker died on the mountain in 2003 after falling 500 feet.

The trail crosses slopes that bloom with balsamroot and other wildflowers, most notably in May. The route passes the site of a fire lookout built in 1931 and rebuilt in 1952, then dismantled in 1967. Hikers share the path with leashed dogs year-round.

The trail climbs about 2,800 feet over 6 miles, with the first half-mile especially steep. It is open year-round, but upper sections may hold snow in winter. Horses, mountain bikes and wheelchairs cannot use it; dogs must be leashed. Parking at the trailhead requires a Northwest Forest Pass, and a small permit fee applies in spring.

The fire lookout built in 1931 and rebuilt in 1952 was dismantled in 1967, once roads and airplanes made it obsolete. A hiker died on the mountain in 2003 after losing her footing and falling 500 feet. The trail begins at milepost 53 on Route 14, about 9 miles east of Stevenson.
