Located just north of Cape Perpetua Visitor Center, the Devils Churn Day Use Area shows the mighty power of the sea. Crashing waves and the constant churning of the ocean carved a deep chasm called Devils Churn. Over thousands of years the constant force of the ocean waves has made the opening more than 80 ft (24 m) wide. As the tides come in and the waves crash upon the volcanic rock, ocean spray can reach as high as 200 ft (61 m) into the air.
There is one hiking trail that can be accessed from the Devils Churn Day Use Area and it is the Trail of Restless Waters. The paved .4 mile (.6 km) trail follows the coastline offering views of crashing waves, volcanic tidepools and wind sculpted spruces. There is potable water and restrooms at the day use area. Recreation pass or $5 day use fee reqiured.
