For a quick one-mile jaunt in Montaña de Oro State Park, hike down Dune Trail to Hazard Canyon Reef. At the bottom of this oceanfront ravine there is a rocky shoreline graced with engaging tide pools. Explore up or down the coast to extend your stay, or settle in for a picnic on the sandy beach. The postcard views of Morro Rock are a good reason to stick around.
The trail begins from a dirt pullout in a eucalyptus grove along Pecho Valley Road north of the Montaña de Oro State Park Visitor Center. North is the direction you’ll hike down a dirt track into Hazard Canyon. The ocean appears in no time, and you will reach the bottom of the ravine after a third of a mile. A few wooden steps assist with the 100-foot descent, and a boardwalk across the wetlands at the mouth of the canyon ensure that you don’t have to mess with any mud. To reach the ocean, pass through a gap in the dunes just beyond an unmarked 4-way junction (another section of Dune Trail continues up the coast to the right and a path comes down from the dunes to the left (more on that later)). Beyond the canyon, the trail continues a short distance to Hazard Canyon Reef, a rocky point along the shoreline.
The trail fades and the exploration begins. Step out on the rocks to examine pools housing sea stars, hermit crabs, and sea anemones. Watch waves crash against the rocks, filling and draining the blue pools. North of Hazard Canyon Reef, there is a sandy line of dunes sheltering Moro Bay. A few miles up the sandy beach is the iconic Moro Rock, giving the tide pools at Hazard Canyon Reef a dynamic backdrop.

An alternate route to Hazard Canyon Reef is to head west from the north end of the lot on a path across the dunes. After reaching a scenic ocean overlook atop the steep dune wall, angle north along the bluff. When Hazard Canyon appears below, take a precipitous sandy path down into the canyon. This stretch drops 150 feet in less than a tenth of a mile and feels like downhill skiing in the sand. You would not want to attempt this path in reverse, but it can be used to create a loop hike to Hazard Canyon Reef, adding broader views.

To get to the trailhead: From the 101 Freeway south of San Luis Obispo, take exit 200 onto Los Osos Valley Road. Drive a total of fifteen miles northwest toward Montaña de Oro State Park. After 11.2 miles, Los Osos Valley Road becomes Pecho Valley Road and turns sharply to the south. Continue 2.7 miles, entering Montaña de Oro State Park and a eucalyptus grove. Turn right into a large dirt pullout for Hazard Canyon (If you reach Spooner’s Cove and the visitor center, you’ve gone too far). There is usually a collection of horse trailers in the dirt lot. The trail begins from the north end of the lot, labeled simply “beach.”
