Two miles north of Mendocino, Russian Gulch State Park spans nearly 1.5 miles of ocean frontage that bloom with wildflowers in the spring. The park's most famous feature, Devil's Punchbowl, formed when pounding waves forged an inland tunnel and left a hole 100 feet across and 60 feet deep. Boiling waves crash around the cave's interior, producing a reverberant echo. The Frederick W. Panhorst Bridge rises gracefully 100 feet from the bottom of the gulch.
