Dog Mountain rises above the north side of the Columbia River Gorge in the U.S. state of Washington.

The mountain is the site of a popular hiking trail that begins on the north side of Route 14 at milepost 53.

[4] The lookout was built in 1931 and reconstructed in 1952 to watch for fires across the river in Oregon's Mount Hood National Forest.

[9] The trail is open year-round to hikers and to dogs on leashes, although in winter the upper portions may be snow covered at times.

The permits fees, of 1-2 dollars, are to start the spring of 2018 to hike the trail and parking at the bottom requires a Northwest Forest Pass.
