DISTANCE

This is the total round-trip distance of the hike to the nearest 0.1 mile. For the few hikes that are recommended as one-way trips, the mileage is labeled accordingly.

ELEVATION GAIN

This is the total (not the net) elevation gain for the round-trip hike. Once again, one-way hikes are specifically identified as such. Keep in mind that for most hikers the difficulty of a trail is determined at least as much by how far up they go as by simply how far they go.

HIKING TIME

This category lists the approximate time it will take the average hiker to complete the round-trip hike. If a trip is recommended as a one-way adventure, it is so identified, and the hiking time will correspond to the one-way distance.

OPTIONAL MAP

For many hikes, the map in this book will suffice for your trip. However, you may want to carry a contour map of the area to help pick out landmarks and to more closely follow your upward, or downward, progress. This entry identifies the best available contour map for each hike. In many areas the privately produced Green Trails maps are the best because they are specifically designed for hikers, are reasonably up-to-date, and use an ideal scale for pedestrians. When U.S. Geological Survey maps are recommended, the listed maps are in the 7.5-minute series.
