Print maps remain the preferred navigation aid and general reference resource for hiking and backpacking. A good hiking and backpacking map should highlight recreation trails, clearly indicate public versus private land, as well as depict fine-scaled topography and elevation. Other nice elements of a recreation map include mileages from trailheads to trail intersections, depict multi-use versus hiking only trail use designations, and may even show good sources for water and indicate locations for campsites.
