The park is serviced by a 91-mile (146 km) road from the George Parks Highway to the mining camp of Kantishna. It runs east to west, north of and roughly parallel to the imposing Alaska Range. Only a small fraction of the road is paved because permafrost and the freeze-thaw cycle would create a high cost for maintaining a paved road. The first 15 miles (24 km) of the road are available to private vehicles. Beyond this point, visitors must access the interior of the park through concessionary buses. Wonder Lake can be reached by a six-hour bus ride from the Wilderness Access Center. Eielson Visitor Center is located four hours into the park on the road.
