Guadalupe-Nipomo Dunes National Wildlife Refuge
Guadalupe, CA
Guadalupe-Nipomo Dunes National Wildlife Refuge protects four square miles of dune habitat, some of the tallest coastal dunes in California, entered via the Oso Flaco Lake trail rather than a direct access point of its own. It's a genuinely vast, protected ecosystem, worth exploring for the scale of the dunes alone.
The sheer scale of protected dune habitat here is genuinely rare in California, though reaching it means going through the Oso Flaco Lake trail rather than a direct entrance.
How we score beachesEnter through the Oso Flaco Lake trailhead, that's the actual access point into this refuge rather than a separate entrance of its own.
