Montaña de Oro State Park has dramatic ocean bluffs and summits with sweeping views. The park covers over 8,000 acres and has 7 miles of undeveloped coastline, making it a rare treasure on the California Coast. One road leads into the park, entering from the town of Los Osos to the north, which is just west of the city of San Luis Obispo. Visitors can stay overnight at a 50-site campground at the center of the park.

First time visitor should be sure to hike the Bluff Trail, which crosses sea cliffs and coves on the impressive oceanfront.
With more energy, you can hike to a mountaintop like Valencia Peak, Oats Peak, or Hazard Peak. Every summit trail offers great ocean views. Each peak also looks inland across the Irish Hills, which spread beyond the eastern boundary of Montaña de Oro State Park. Hazard Peak in particular provides nice views north up the coast toward Morro Bay and beyond.

Generally speaking, mountain bikers are allowed on trails on the north side of the park, but that seems to be expanding as Oats Peak is now open to bikes as well. Islay Creek Trail and Hazard Peak Trail and also popular mountain bike routes and the Bluff Trail presents an easier ride. Dogs are not allowed on trails in Montaña de Oro State Park.

When are the poppies/wild flowers blooming?
Should be many wildflowers now, though poppies may be scarcer this year because they like drier winters, (which this last was NOT.)
