Katmai National Park – Trails Illustrated
This is National Geographic’s “trail map” of Katmai National Park, part of the well-known Trails Illustrated series. These maps are pretty much the standard for trail maps of the national parks, and many other areas. They are durable, detailed, and very readable. Note that in this case, Katmai has very little in the way of real trails. This is more useful as a route-finding and topographic aid, and is essential for backcountry travel.
