The Mattole area, particularly the Lost Coast beaches, which feature tide pools, pristine beaches and relatively deserted hiking trails, is popular with visitors. At certain times of year, migrating gray whales can be seen from shore, as well as colonies of harbor seals and sea lions. Local residents use the Mattole River for swimming, rafting, canoeing, kayaking and catch and release fly fishing. The South Cape Mendocino State Marine Reserve and Sugarloaf Rock are immediately offshore and are closed to public access.
