This was our first stay at Lake Cachuma. It is well worth it to get a Premium site as they have lovely views of the lake and sunset. We stayed in a larger group site with one other tent couple and the site was huge. There were a few big oaks for shade but otherwise you were on very dry hard packed dirt in the open. Water spigots and Port a Potties as well as bathrooms and showers ( pay showers) were conveniently located throughout the park. There is no real privacy here as sites are all an an open flat and there are not a lot of trees so camping without a shade tarp could be unpleasantly warm. There is no swimming in the lake but there boat rentals and fishing are allowed. Yurts and cabins are also available for reservation. There is a general store at the entrance and a gas station for all your needs. Oh, yes! A word of caution...my daughter put their tent under the Oaks for shade and evidently their were nests of spiders hatching as their tent was literally inundated with hundreds of thousands of spiders! The ranger said he had never seen anything like it. You might want to think twice about being under the trees, or at least know what spider nests look like!
