Ingalls Lake is an extremely popular destination in the Alpine Lakes Wilderness, Washington state. For that reason I have been hesitant to post and identify these photos. Those looking for solitude and wilderness experience should avoid this area, with the possible exception of fall, winter and spring. Warning: Only the most hardy hike/climb here in winter. This lake, nearby Ingalls Peak, and the entire area might see 200 to 300 hikers on a summer weekend. Ingalls Peaks and Mount Stuart are climbing destinations reached from the Ingalls Way Trail. No camping is allowed at the lake and no dogs are permitted.
