Dog Mountain rises above the north side of the Columbia River Gorge in the U.S. state of Washington. The base of the mountain is in Skamania County along Washington State Route 14, about 9 miles east of Stevenson. From its base at 150 feet, it climbs steeply to an elevation of 2,948 feet. The mountain is the site of a popular hiking trail that begins on the north side of Route 14 at milepost 53. The 6-mile (9.7 km) trail winds through heavy forest to meadows and the site of a former fire lookout. After climbing steeply for about the first half mile, the trail splits into two forks that meet again at the summit. Attractions include views of the Columbia Gorge, Mount Hood, and wildflowers, especially in May. Flowering plants along the trail include chocolate lily, woodland star, fairy slipper, long-spurred violet, and yellow fawn lily. Hazards include poison oak, rattlesnakes, and steep slopes. The trail's difficulty caused one writer to describe it as "a grueling hike".
