DIAS RIDGE TRAIL

Dias Ridge

A long-time favorite destination for recreation users, Dias Ridge—named after one of the Portuguese dairy ranchers who once owned swaths of the West Marin hills—is on a ridgeline above Muir Beach and offers breathtaking views of the Pacific Ocean and Marin Headlands.

Completed Site Improvements

The newly completed segment of the multi-use trail, which bridges a gap in the Bay Area Ridge Trail, replaces an old ranch road and establishes a more sustainable footprint that complements the landscape and reduces erosion impacts.

Part of a larger effort to revitalize the Redwood Creek watershed, the improved Dias Ridge Trail has re-opened to the public after extensive restoration work.

  • 1.5 miles of new trail
  • Decommissioned "social" trail to protect habitat
  • Replanted native vegetation

Future Actions

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

  • Enhancing trail safety and multi-user compatibility on the trail by improving drainage and line-of-sight clearings on blind corners
  • Monitoring tread improvements
  • Assessing trails after recent rains and identifying wet water crossings
  • Improving fencing on curves for cyclists and equestrians
  • Reviewing signage on trail distances, destinations, park regulations, topography, and alignment
  • Restoring vegetation and habitat
  • Planting and monitoring approximately 20,000 native plants on the trail grown at the Marin Headlands Native Plant Nursery for the trail

In addition, the National Park Service and Parks Conservancy are taking the lead in restoring the tidal lagoon at Muir Beach and improving the former Banducci farm site.
