For years, an old ranching road was the only access point to Dias Ridge for hikers, bikers, and equestrians. Heavy use of this road caused erosion and deposited sediment in Redwood Creek—damaging the spawning grounds of the endangered coho salmon and threatened steelhead trout.

The National Park Service and Parks Conservancy took a landscape-level approach to removing the eroded road and creating the new multi-use trail. This approach not only results in a better visitor experience but also reduces erosion in the lower watershed, ultimately enhancing the diverse coastal habitats in the area.

This segment of trail also bridges a gap in the Bay Area Ridge Trail and establishes a more sustainable footprint that complements the landscape.

In addition to creating 1.5 miles of new trail, Parks Conservancy staff and volunteers have planted over 30,000 native plants along the re-routed Dias Ridge Trail.

Ongoing Actions:

The National Park Service, Parks Conservancy, and California State Parks will continue improving the visitor experience on the trail by:

  • Enhancing trail safety for cyclists, hikers, and equestrians.
  • Ongoing assessment of trail conditions through wet and dry seasons.
  • Restoring vegetation for plant and wildlife habitat.
  • Planting and monitoring approximately 30,000 native plants on the trail, grown at both the Marin Headlands and Redwood Creek Native Plant Nurseries.
