For routes that begin and end at the same spot—that is, a loop or out-and-back—the vertical gain exactly matches the vertical descent. With a point-to-point route, the vertical gain and loss will most likely differ, and both figures are provided in the text.

The more strenuous routes have an elevation profile, an easy means for visualizing the topography of a route. These profiles graphically depict the elevation throughout the length of the trail.

Top Trails Difficulty Ratings

1 A short trail, generally level, that can be completed in 1 hour or less.

2 A route of 1–3 miles, with some up and down, that can be completed in 1–2 hours.

3 A longer route, up to 5 miles, with uphill and/or downhill sections.

4 A long or steep route, perhaps more than 5 miles or climbs of more than 1,000 vertical feet.

5 The most severe, both long and steep, more than 5 miles long with climbs of more than 1,000 vertical feet.

Surface Type

Each trail entry provides information about the surface of the trail. This is useful in determining what type of footwear or bicycle is appropriate. Surface type should also be considered when checking the weather—on a rainy day a dirt surface can be a muddy slog; an asphalt surface might be a better choice (though asphalt can be slick when wet).
