Oso Flaco Lake is a hidden natural gem. Oso Flaco lake is hidden in the Pismo Dunes Natural Preserve and it is surrounded by farm land. Situated about 30 minutes south of Pismo Beach and about 10 minutes north of the small town of Guadelupe, Oso Flaco Lake is hard to find. There is only one small street sign on Cabrillo Highway. If you don’t know what you’re looking for, you will definitely miss it. Once you get to the sign there is another five to ten minutes drive through farm lands until you get to the Oso Flaco park. But what a beautiful place Oso Flaco Lake is! It is nestled among sand dunes and the state has built a beautiful walkway that goes almost over the entire lake. Then you can continue walking all the way to the ocean. You get an amazing view at the end of the walkway. It’s just a beautiful place!
