Oso Flaco Lake
Oceano, CA
Oso Flaco Lake combines a genuine freshwater lake with a boardwalk trail continuing on to the ocean beach beyond the dunes, a two-for-one stop that most Pismo area visitors skip entirely. The lake itself draws real birdlife, worth the stop even before reaching the sand.
The genuine combination of lake and ocean beach in one boardwalk walk is rare and worth the stop, though most Pismo area visitors skip it entirely in favor of the more famous main beach.
How we score beachesWalk the full boardwalk out to the ocean beach rather than stopping at the lake, the dune crossing beyond it is a genuinely worthwhile extension of the same trail.
A day use fee applies; the exact amount is best confirmed at the entrance.
A boardwalk crosses the lake and dunes to reach the ocean beach.
Dogs are not permitted anywhere in the Oso Flaco Lake day use area, including the trails, boardwalk, and beach.
Fall and winter bring the most birdlife to the lake, while fog is common most mornings year round.
