This beautiful small harbor is a truly unique setting on the central coast. The original breakwater was built between the 1890s and 1913 to protect the harbor from large waves and heavy surf, and it still serves its purpose today. Itโs not as touristy as some other locations, making it an ideal spot to take a break and walk on the pier. Itโs also a fantastic place to see the sunset if youโre lucky enough to be here in the evening.

The lake is open to the public only during the trout fishing season (last Saturday in April to November 15th).
