Montaña de Oro State Park preserves 8,000 acres along the picturesque coast of San Luis Obispo County. This slice of Big Sur is located between Avila Beach and Morro Bay, and is a popular destination for beach-goers, hikers, mountain bikers, and horseback riders. The dramatic shoreline and thousand-foot mountains provide a scenic setting for a host of great trails, including this level 3.4-mile out and back hike across the coastal bluffs of Montaña De Oro. The Bluff Trail passes tide pools and beaches, and a magical rocky coastline.
From a parking area on Pecho Valley Road, just past the Montaña de Oro Visitor Center, and across from the trailhead for Valencia Peak), follow the signs for Bluff Trail and begin hiking south over a short wooden bridge. The wide dirt trail turns toward the sea, venturing out to Islay Point. To the north is a nice view of Spooner’s Cove, home to a popular beach located below the visitor center.
Continue south across the bluff through low brush with coastal views. Cyclists, joggers, and families pushing BOB strollers share the trail, which arrives at Corallina Cove after half a mile. A short spur descends to this small beach with a tide pool full of interesting sea creatures. Children can scour the rocks, spotting sea anemone, hermit crabs, and starfish. This popular destination makes a family-friendly 1.2-mile round trip hike.
There is more rugged coastline to explore further down the trail. From Corallina Cove, head directly inland and come to a junction alongside a bridge the crosses a small canyon above Corallina Cove. Straight head, a trail circles back to the start. To explore more of the Bluff Trail, turn right and cross the bridge. In the canyon below, you may spot nasturtiums blooming in the spring. The Bluff Trail heads south again, serving up bold ocean views. The main trail is complimented by smaller footpaths that weave across the bluff for more intimate looks at the beautiful coast. The pounding waves cut channels into the rocks. In certain conditions, you might even spot a blowhole.

Half a mile past Corallina Cove comes another popular tide pool, Quarry Cove. There is a picnic table just off trail sitting above a rocky beach marking the spot of the tide pools.
Beyond Quarry Cove, the coastline somehow continues to become more dramatic, leading up to Grotto Rock, one of the more wondrous wonders along this wonderful coast. The tall stone island stands resolute within a rocky cove, fighting valiantly against the ceaseless forces of erosion. Most incredible, cavernous waterway cuts through the base of Grotto Rock and water can be seen flowing clear through the dark tunnel. Somehow Grotto Rock has avoided crumbling into the sea. It is an impressive formation, and a highlight of the hike. Take the footpath along the point south of Grotto Rock to gain the best perspective.
A quarter mile past Grotto Rock, and 1.7 miles from the start, Bluff Trail comes to an end. A connection trail continues for 0.4-miles to the left, inland toward Pecho Valley Road, where it meets a parking area for Coon Creek Trail and Point Buchon Trail. If you are not hiking further, turn around and make your way back along Bluff Trail. The views are equally rewarding in the opposite direction.
