The Lanphere and Ma-le'l Dunes make up the largest and best quality sand dune ecosystem representing coastal dunes from this area. Remarkably undisturbed, yet easily accessible, containing an outstanding variety of dune habitats and associated wetlands. These habitats contain virtually all the species of vascular plants of dune sytems, plus a number of rare species. The site is very scenic and affords visitors an inspiring view of a natural coastal ecosystem.

Because of the fragile nature of dune habitats, the Lanphere Dunes Unit is accessible by permit or guided tour only.

To obtain a permit visitors must first attend a guided tour. Contact Friends of the Dunes (707) 444-1397 for a guided tour schedule

Due to the nature of the habitat, many of the trails at the Lanphere Dunes are not suitable for individuals with mobility concerns. There are steep unstable sand surfaces, narrow uneven footpaths and steep irregular steps without handrails. Please keep this in mind when planning a visit to the dunes.
