The Susitna Valley is about 100 miles north of Anchorage and has one road passing through it, the Parks Highway. The Alaska Railroad also runs through the Susitna Valley, with a depot in Talkeetna. The main secondary roads in the area are the Talkeetna Spur (which connects the Parks Hwy to the historic town of Talkeetna) and the Petersville Road (which goes west for many miles from the Parks Hwy at Trapper Creek). There are other gravel roads, but much of the area is not accessible by road. Airplanes on floats or skis, ATVs, dog sleds, and snowmachines are commonly used methods of transportation to these remote properties.
