One of my favorite hikes in the past was to hike up the North Fork Teanaway (Esmerelda Basin) trail and then walk the ridge to the south summit of Ingalls Peak (above, the ridge for approach is on the left). It’s an moderately easy hike and can be made more interesting by continuing down the other side to the Long Pass Trail and returning to the trailhead with only a short double back.
The view from the summit is wonderful, with the south face of Mt Stuart being the highlight. Stuart is the highest non-volcanic peak in Washington … and attracts a host of serious climbers. I prefer the more enjoyable saunter up South Ingalls.
Also from the summit, you have a stunning view north along the spine of the Central Cascades (below), including views of two of the Cascade volcanoes: Glacier Peak (on the right) and Mt Baker (in the distance on the left). Mt Rainier and Mt Adams are visible to the south (weather permitting).
