After winding over rolling hills and through the Anderson Valley, motorists traveling along Highway 128 suddenly enter an eleven-mile-long redwood tunnel to the sea. The redwood forest along the Navarro River is a magnificent sight. Visitors to the Navarro River Redwoods State Park can enjoy picnicking, swimming, and camping at the Paul M. Demmick campground. The park is popular with anglers, canoeists, and kayakers in the late winter and spring. Second growth redwood groves stretch the length of the park. They are home for raccoons, black-tail deer, and river-oriented birds such as the belted kingfisher. The weather can be changeable; layered clothing is recommended. Unlike coastal parks, summers may be very warm.

This is located on the Northern cliffs just above the mouth of the Navarro River. There is clear and obvious parking on the ocean side of State Highway 1. Trails lead to the cliffs from there. The walk is mostly cliff and ocean viewing. Mendocino Headlands State Park is better, but this area is very nice also. Watch your step at cliffs edge.
