LOOP, SEMI-LOOP, OUT-AND-BACK These designations identify the type of trip. Loop and semi-loop routes, the most common in this book, have been designed to minimize steep downhill sections whenever possible.

HIKING TIME

An estimate of the time it takes an average hiker to complete the trip, including stops along the way.

TOTAL ELEVATION GAIN/LOSS

Approximate sum of all the uphill and downhill segments of the trip (includes outbound and return legs for out-and-back trips).

DIFFICULTY

A subjective rating based on distance, total elevation gain/loss, and terrain. Here is an explanation of the four categories:

EASY Short trips with little or no elevation gain.

MODERATE Trips of several hours or more, with some ups and downs but no significant elevation changes.

DIFFICULT Extended trips with significant elevation changes.

VERY DIFFICULT The longest, most rigorous trips in this book.

TRAIL USE

BACKPACKING OPTION A few Bay Area parklands have campsites along or near the trip as described. Most of these require advance registration, as noted in the text.
