On Sixmile Creek near Hope, offers one of the best whitewater trips in Alaska. Dropping over 50 feet per mile, Sixmile flows out of the Chugach Mountains and cuts through three separate canyons. Towering walls with cascading waterfalls and awesome whitewater make this a river runner’s dream. It is a highly technical river and it requires physically fit participants. Chugach offers less demanding trips so be sure to check them out at mile 7.5 on the Hope Road.
