The map and summary information list the trail endpoints (either a city, street, or more specific location), with suggested points from which to start and finish. Additional access points are marked on the maps and mentioned in the trail descriptions. The maps and descriptions also highlight available amenities, including parking and restrooms, as well as such area attractions as shops, services, museums, parks, and stadiums. Trail length is listed in miles.

Each trail bears a roughness index rating from 1 to 3. A rating of 1 indicates a smooth, level surface that is accessible to users of all ages and abilities. A 2 rating means the surface may be loose and/or uneven and could pose a problem for road bikes and wheelchairs. A 3 rating suggests a rough surface that is only recommended for mountain bikers and hikers. Surfaces can range from asphalt or concrete to ballast, cinder, crushed stone, gravel, grass, dirt, and/or sand. Where relevant, trail descriptions address alternating surface conditions.
