Pasadena sits at the gateway to the San Gabriel Mountains, where city dwellers trade sidewalks for trails within minutes. Year-round hiking options range from waterfall chases after winter rains to shaded canyon walks and historic ridge climbs. Always check fire closures and grab an Adventure Pass before heading into the national forest. The best trails reward you with vistas stretching from downtown LA to snowy peaks.
