River runners will want to head inland. It will take you five to ten days to run the length of road-accessible Copper River's Class I and II waters. Any Mountain Wrangell St. Elias is land set aside to preserve mountains. And mountain experiences there most certainly are that climbers relish. In most cases, only the most technically proficient need apply.
Access is limited to plane drops, rescue operations are minimal, and the elements are brutal.
If you're not up for the full-gear crunch, a flight to Jaeger Mesa leaves you a walk up Jacksina Creek and a scramble up the southern slopes of Mount Gordon to awesome views. There are plenty of other nameless peaks that may never have been climbed. You won't want to take a road bike or sports car on the rough surfaces, but mountain bikes and jeeps will be a joy. In addition, for mountain bikers there are dry creeks along Nabesna Road when you want to get away from traffic. Beware of washouts and be prepared for extreme conditions wet, mud, dust, rock, and uneven surfaces.
