Last summer me and my son Gabriel, who was six at the time, Hiked up Edmonds path, summited Eisenhower, Monroe, then to Lakes of the Clouds hut. The next morning after breakfast, we hiked around Washington (too cloudy and windy, plus we did that peak the summer before) and summited Jefferson and spent the next night at Madison Springs hut. It took us about seven hours to do seven or so miles. We went at a nice slow pace and he loved it.
