San Diego County Adventure Map

Hikes are color coded by difficulty (using Modern Hiker and SoCal Hiker’s methodology):

Easy Hikes marker GREEN markers are short nature trails, gently-graded pathways, and routes that are relatively easy.
Moderate Hikes marker BLUE markers designate the “moderate” difficulty hikes. These trails may be lengthy, or have areas of intense elevation gain. They may require some scrambling, but most of these trails are easy day hikes that can be done by anyone in fairly decent shape.
Strenuous Hikes marker RED markers are for the “strenuous” trails. These are long, leg-busting paths that will require lots of time and effort. Some of these trails may venture through dangerous areas and require river crossings, backcountry orienteering, or more serious rock scrambling. In other words, if it’s your first time on the trail, don’t pick one of these.
