Because there are very few maintained trails within the park, travel through dense brush, along steep scree slopes, and across fast and cold glacial streams and rivers should be expected. For most routes, map and compass reading skills are essential. Weather in these mountain ranges can vary to extremes in relatively short time periods. It is best to expect (and prepare for) almost any possibility with a variety of layerable clothing (polypropylene, wool or pile), raingear, and extra food. Summer snow storms may occur at elevations of 4,500 feet and above.
Trip Planning
A successful hiking trip requires adequate planning. You should be prepared for everything and should not count on aid or rescue from others. Here, you will be on your own. Caution and good judgment are key ingredients for a pleasant expedition. For many hikers, hiring the services of a local guide will make the trip safer and more enjoyable. In general, the areas above tree line (~3,000') afford the easiest hiking and best views. These areas are often accessed by chartering a flight to one of the many possible "bush" landing strips. Note that there are many more places to land than are shown on maps. Air taxis will often land on gravel bars or on the tundra. The routes depicted on the "Trail Illustrated" map are the most popular.
Topographic Maps
Don't Leave Home Without Them! Be aware that many of the historic trails shown on older U.S.G.S. maps are often non-existent or overgrown. If you prefer not to see others on your trip, ask a ranger or pilot about some of the lesser known areas. A list of licensed air taxi operators is available from the park. Be flexible and prepared for alternative destinations. Your air taxi or the Park Service may know of high water conditions, wildlife hazards or overcrowding in an area and may encourage you to choose an alternative at the last minute.
