Further south along Highway 1 is Morro Bay, where you can get up close to Morro Rock via Coleman Park. The rock dominates the coast line so it was nice to be able to walk around part of its base for a different perspective.
Finally, if you head north to San Simeon you can visit not only Hearst Castle, but also the elephant seal rookery at Piedras Blancas. We were able to see hundreds of elephant seals lying on the beach as it is currently molting season. It was such an amazing sight and one of the highlights of the trip.
