A lovely overnight backpack along part of the Pacific Crest Trail. A rope swing over a cool pool. A hot lunch on the trail by a tall waterfall. Camping in a canyon at an old Indian summer hunting camp. Plus practicing the usual scout skills of pitching tents, building fires, cooking meals, and telling jokes around the campfire. Cooper Canyon is one of our favorite backpacking trips in the summer after the snow melts high in the San Gabriels.
