We were there in the middle of summer in the dumpster fire year of 2020. Make sure you get the correct weather report of ‘Cachuma Village’ and not assume it is the same climate as the much cooler Santa Barbara (15 degrees difference).
There are hundreds of campsites and many have RV hookups. I found the following YouTube video helpful when reserving a space. We were glad we picked a space that was under the canopy of two mature trees. https://youtu.be/sDWHOIo66F4
Although the lake looks beautiful, it is only a boating lake. There is no swimming nor paddle boarding allowed on the lake. There were plenty of fishing boats there as well as rentable pontoon boats.
There is not much of a hiking experience at the Lake except to walk around it. As we walked around, we loved seeing how other campers set up their camps since we’re relatively new campers.
We brought our dog and she loved it despite having little balls of thorns attach to her paws like magnets. (See picture). We ended up having to just carry her.
We’d love to go back again but next time we’ll make time to rent a boat and go fishing ON the lake.
