The 90-acre Los Osos Oaks State Natural Reserve protects a pocket of 800-year-old oaks near San Luis Obispo, California. Los Osos Creek Trail, Chumash Trail, and Oak View Trail loop through the park presenting easy hikes between 0.75 and 1.5 miles. The trails pass beneath (and sometimes between) the gangly branches of pygmy oaks, offering quiet hikes through a shady grove.
A bridge into the oaks
The quick stroll begins from a free parking area along Los Osos Valley Road. Enter the grove of coast live oaks, crossing a wooden footbridge to reach a three way split. The heart of the oak forest lies straight ahead on the east side of Chumash Loop Trail. Further to the east is Los Osos Creek Trail, which passes the near stagnant waters of a seasonal stream. The west side of Chumash Loop Trail breaks off to the right and all three paths reunite further to the south. At that point, the trails also join Oak View Trail, which offers another loop trail heading further south through more oaks and chaparral woodlands. If these trail options sound overwhelming, don’t be concerned. Each trail offers a similar experience hiking beneath the oaks. See the map in the park brochure for a better understanding of the trails.
Start down any trail you like and make your way into the grove. Century old coast live oaks offer a dense canopy overhead. Grown upon ancient dunes, these oaks are stunted to about 30-feet tall. The oaks have broad sprawling limbs decorated by lace lichens. The mossy growths hang like a Santa Clause convention of white beards, adding further charm to the forest.
Oaks above Chumash Trail
If you turn left on Los Osos Creek Trail, be sure to follow the trail when it curls to the right. If you remain parallel to the road, you will come to a sudden dead end on the bank of the creek’s murky pools. The preserve has a few unnamed side paths, but the major junctions are well marked, like intersections at the south end of Los Osos Creek Trail with both Oak View Trail and Chumash Loop Trail. Returning via either side of Chumash Trail for a 0.75-mile hike with 25 feet of elevation change. Oak View Trail circles further to the south exploring more chaparral and oaks. No matter how far you hike in Los Osos Oaks State Natural Reserve, make a point to include a stroll on the section of Chumash Loop Trail that passes through the center of the park. Here long gangly oak branches spread across the trail to creating interesting obstacles that enrapture you in an enchanting world. Dogs are not allowed, but no fee or permit is required for this short hike in Los Osos Oaks State Natural Reserve, so get out and enjoy!
