The San Mateo Canyon Wilderness was designated a wilderness in 1984. Within its 39,540 acres you will find over 60 miles of hiking trails. Enjoy the geology, flowers and trees, birds and mammals, wonderful views, and... its solitude.
Rugged mountains covered with chaparral and coastal sage dominate the landscape. One of the most attractive aspects is the many deep drainages supporting areas of lush vegetation. Oak woodlands cover the balance of the wilderness land base.
Average annual rainfall ranges between 15-20 inches, occurring primarily
during winter and spring. Temperatures are moderate in spring, fall and winter,
but can be very hot during the summer. There are no large bodies of water within
the boundaries, but small pools can be found in San Mateo Canyon. Though close
to major population centers, the wilderness is lightly used; just waiting to be
discovered and explored by you...
Please use the area in a manner which will leave no trace, so the next visitors will also find the beauty and solitude they seek. The natural environment of the wilderness may seem rugged and harsh, but it is a very fragile system, slow to recover once disturbed.
Southern California is often described as "seasonless," but there are many noticeable changes throughout the year. Coastal ranges can be hot and dry in summer, cool in fall with leaves changing color, receive heavy downpours during winter, and turn lush and green with blankets of wildflowers in spring.
Spring--the most beautiful season. Wildflowers abound, everything is green, and water is plentiful. Birds are everywhere and, if you look carefully, you may see a variety of animals, reptiles and amphibians.
Summer--grasses turn gold, flowers fade, most of the streams and waterfalls become mere trickles or dry up. By mid-day, open stretches of trail become very hot and dry. This is the time to seek out cool canyon bottoms or climb to ridgelines for ocean breezes.
Fall--the reds and golds of oaks and sycamores. Temperatures begin to cool and you can feel winter approaching. This is an excellent time to explore.
Winter--rains from delicate drizzles to torrential down- pours. This is the time when hikers must watch for flash flooding in the narrow canyons.
Water is crucial when hiking in the wilderness. Adults require at least 2 quarts daily to prevent dehydration. More water is needed in hot weather or during strenuous activity. When planning even the simplest day hike, be sure that every member of your party has plenty of water.
Only during wet winter months can you expect to find natural sources of water. If you plan to use spring or stream water, be sure to filter, boil or chemically treat it for at least 5 minutes. Remember, the amount of water you carry can mean the difference between an enjoyable trip, or a disaster. The San Mateo Canyon wilderness provides permanent or seasonal habitat for 139 bird species, 37 mammal species, 46 species of reptiles and amphibians, and 7 species of fish.

Even on a hot summer day, life abounds. Lizards are easiest to spot, sunning on the rocks. Without much detective work, you might find footprints of deer, coyotes, skunks or the many kinds of mice that live in the chaparral, cool riparian areas or oak woodlands.
The wilderness is home to rattlesnakes, but non-venemous varieties are more prevalent. You might see colorful red coachwhips, red-sided garter snakes, or king snakes. These reptiles are fascinating to watch.
Mountain lions are found in many areas, but seeing one is a rare treat. They are chiefly nocturnal and are most often spotted in early morning or at dusk. The most common evidence of a lion's presence is a broad, clawless footprint in the dust or mud. When you hike in lion territory, carry a big stick and make noise. If you should encounter a lion, don't run--stand firm and yell. Remember reasonable safety practices can make a chance encounter with a mountain lion a positive event and a once-in-a lifetime opportunity for you and your family.
Birdwatchers rejoice! Abundant bird species provide an excellent birding experience and all habitats...brush, chaparral, oak woodland, creek, canyon, and rock outcroppings... are accessible by the trails.
Amateur and experienced botanists can enjoy the array of plant communities... chaparrals, coastal sage, riparian and oak woodlands. Spring wildflower displays are spectacular. On one spring jaunt, a hiker noted over fifty varieties of shrubs and wildflowers.
