Corvallis to the Sea Trail

Corvallis to the Sea Trail is a 62 mi long hiking, bicycling, and equestrian trail in Western Oregon (United States) which links the Willamette Valley to the Pacific Ocean. It connects between Corvallis and Ona Beach. As of May 2019, the eastern half (about 30 miles) is open and crosses a patchwork of public and private land. The remainder of the trail traverses Siuslaw National Forest with 6 mi requiring trail to be built. The trail was set to open on June 6, 2020, but is delayed by the COVID-19 pandemic.

The project to establish the trail had more than 40,000 volunteer hours and $20,000 in donations.

The effort began in 1974 but failed due to private property permission difficulties. In 2004, the C2C partnership was created and it proved able to work successfully with Siuslaw National Forest officials.
