About Green Knob

Green Knob is a summit of 3,100 feet in the Mt. Adams Ranger District of Gifford Pinchot National Forest in Washington, about 7.5 miles from the town of Stevenson. Summer is the most comfortable time to visit. Typical averages from a nearby weather station show July and August highs around 84°F with lows near 50°F, and the summit sits higher than that station, so expect it to run a little cooler. Sedum Point and the Sedum Ridge Trail are both within about a mile and a half. Climbers can head to Rock Creek Cliff, about 3 miles away, and Beaver Campground offers a place to stay roughly 4.7 miles off.
