While most trails are maintained, many still remain rugged, with steep climbs, weather-beaten culverts, and rocks that can be difficult even for the most experienced hikers.
Coon Creek, Islay Creek and Hazard Creek Trails take you through the wooded areas of the park. The four-mile (roundtrip) Valencia Peak Trail reaches the top of the peak and offers inspiring views of the central coast. The Bluff Trail brings you to overlooks above the coves and sea caves of the park.
Please remember: Dogs are not permitted on any of the trails in the park. Camping is allowed only in designated sites. Poison oak flourishes throughout the park. And it's a good idea to pack a picnic lunch and bring water, as there are no concession stands in the park.
