The Pasayten Wilderness borders Canada and is south of Manning Provincial Park and Cathedral Provincial Park. It is next to Ross Lake National Recreation Area and North Cascades National Park. The northern end of the Pacific Crest trail ends in the Pasayten. It is varied terrain and wilderness with drier basins to the east and rugged mountains to the west.
Horse packers and llama packers take groups into the wilderness and a favored spot is Lauden Lake in Horshoe Basin. Rising above Horsehoe basin, to the north and on the the Canada border is the massive Arnold mountain.
Every attempt has been made in the Jim Johnson books to depict the wilderness accurately. It is a beautiful area and one of the least visited wilderness areas in the lower United States.
