Located just off the California shore, the Channel Islands are home to many unique species of flora and fauna. National Geographic's Trails Illustrated map of Channel Islands National Park covers with unparalleled detail the five islands that encompass the park, including The Nature Conservancy area of Santa Cruz Island and the many State Marine Reserve Areas surrounding the islands. Expertly researched and created in partnership with the National Park Service and others, the map provides background information of the park and of each individual island along with its regulations and guidelines. In addition, information regarding transportation to the islands is given as well as land (hiking), water (swimming, snorkeling and diving) and boating (and kayaking) safety warnings.

Each island is shown with a trail guide, listing trail start and destination points, distances and difficulty. Trails are mapped with mileage markers and coded according to trail type. Island roads, which can also be used use for hiking, are shown as well. An inset map of the Scorpion Area provides extra detail of this popular area. The map includes contour lines, elevations, labeled peaks, selected waypoints, water features and areas of wooded cover. Moreover, many recreation features and facilities are pinpointed, such as ranger stations, campgrounds, restroom, picnic areas and historic buildings.

Every Trails Illustrated map is printed on "Backcountry Tough" waterproof, tear-resistant paper. A full UTM grid is printed on the map to aid with GPS navigation.
