Oso Flaco Lake Nature Trail     


Guadalupe--Oso Flaco Lake Natural Trail is accessible from Oso Flaco Road off Highway 1 north of downtown Guadalupe. A guard hut and restrooms were installed several years ago and a parking fee of less than $5 is now charged to help pay for the attendant and upgrades created to attract visitors. A road sometimes covered in sand makes for a great adventure.

The Nature Trail leads pedestrians on a mile-long boardwalk which parallels the Oso Flaco Lake and Creek flowing into the Pacific Ocean. While it is part of the Oceano Dunes State Vehicular Recreation Area, no vehicles are allowed on this protected portion of it. Access to the all-terrain vehicle driving area is just north of thiss  region and must be accessed in Oceano.  



entranceThe entrance to Oso Flaco is indicated by a sign amongst the wildflowers next to a field of food crops. Spectacular sand dunes and lush vegetation are a few of the sites leading to the beach. 



Small bobcats, coyotes and fox thrive in a forest surrounded by rich farm land. The wild animals shy away from humans though you can usually see them darting through the brush if you look carefully. The protected region is also home to Western snowy plovers and California least terns which nest in the dunes near the ocean. Visitors are asked to stay below the high tide line while on the beach to not disturb their mating and nesting activity. Ask at the kiosk about Nature Conservancy docent-lead walks scheduled several times per month.

Site of the 1923 Filming of the Ten Commandments 



About 60 years after the Ten Commandments movie was made, filmmaker Peter Brosnan discovered an entry in Cecil B. DeMille's autobiography in which he talked  about buried sphinx's in the Guadalupe Dunes. What has been found through archaeological efforts is the buried movie set buried 6 feet deep in the sand and spanning the length of 2 football fields. Final mapping and archaeological excavation of the site will occur as funds become available.
