Oceano Dunes State Vehicular Recreation Area, Oso Flaco Lake Natural Area - Site # 298
PremiumPremium - the most significant sites, worth visiting if you have limited time. Premium sites have high wildlife values year-round, staff on site, interpretive programs and/or displays, and well-developed facilities.

Background: The natural area provides a unique trail experience through the dune complex, where visitors will walk over a mile-long footbridge and planked boardwalk through riparian areas of willows and wax myrtle, over a freshwater lake, and through dune scrub habitat ending at the beach. Birdwatchers delight in locating different species in the variety of habitats. Hundreds of waterfowl visit the lake daily during winter months and resident marsh birds can be seen on the lake edge. Abundant wildflowers such as silver bush lupine, Indian paintbrush, and Hooker's evening primrose bloom throughout the spring and summer. The tall dune, Coreopsis Hill, which can be accessed from the trail, is covered with a burst of yellow giant coreopsis during the spring.

The Habitat: Beach foredune (35%), dune scrub(45%), fresh water lake (5%), arroyo willow riparian (10%), marsh (5%)

The Experience: Many rare and endemic species only found within this unique dune system are present.

Wildlife and Where to Find It: From paved trails, or boardwalk from parking lot to beach, approximatley one mile one way.

Viewing Tips: Birding - year around;
wildflower viewing - spring and summer.

Site Notes: When walking through the wooded area along the paved road toward the lake, listen for songbirds and look for raccoons (don't approach!). Walk through marshlands, pass tall tule grasses, which the Chumash Indians used to build their houses, and on the bridge over Oso Flaco Lake. Portola's expedition party in 1769 caught and ate 'un oso flaco' ,a skinny bear, giving the lake its name. There is a diversity of animal life to be viewed from the lake including migrating and resident native birds. Look along the edge of the lake for soras and bitterns. The beach is a nice place to stroll, but bring a jacket because it can be cold. Various shorebirds can be seen at the shore and at the Oso Flaco Creek edge. The beach is popular with fisherman, surfers, and for picnicing. During the winter from October to February 29th kids can have sand dune sliding fun in the dunes near the beach.
