Big Creek Natural Reserve

Using The Reserve

Visiting Big Creek Reserve requires an approved application for research or educational purposes. Applications are submitted through the UC Natural Reserve System Reservations System (RAMS).

NOTICE: Big Creek Reserve is currently inaccessible to non-residents and non-site-dependent essential work. The Regents Slide, located at MM 27.6 between the two entrance gates, has blocked Highway 1 and access to Big Creek Reserve is limited while it is within the Caltrans Emergency Highway 1 closure. Please only submit a visit request for site-dependent project purposes, i.e. projects that cannot be done anywhere but at Big Creek Reserve.

Caltrans estimates removing the closure at the end of March 2026. Requests for reserve use that are not site-dependent projects may be considered after the closure is lifted.

Docent-led Tours have been postponed until Highway 1 opens

    Trail Crew Campaign

    The Dolan Fire and subsequent winter storms wreaked havoc on Big Creek’s trail system. A large proportion of what was a 22-mile trail network has been damaged. Our trails provide important access to the biological, geological, and cultural diversity that are vital for learning and research. Please help us hire a trail crew by giving directly to the effort now. Our fundraising goal for this campaign is $115,000.
