Wind Mountain is a nice hike in the Gorge with good views (in clear weather). It's about 2.5 miles round-trip and 1000 feet of gain. There's no pass required at the trailhead and it's often less busy than nearby Dog Mountain.
Head east on Highway 14 from Stevenson, Washington about 6.2 miles to Home Valley. Then turn onto Wind Mountain Road for 1.0 miles to turn right onto Girl Scout Road and go about 0.6 miles. This leads to a large dirt parking area at the end of the paving near 45.7145°, -121.7533°. This is usually the best place to park.
