This is where Phillip proposed, so we may be partial...La Jolla Cove is a beautiful place to walk around, watch sea lions, grab breakfast or a gelato and enjoy a scenic view of the ocean.
Drive all the way down until you hit the dirt parking lot, then walk up to the cliffs and enjoy one of the most breath-taking sunsets the West Coast has to offer. It might be chilly in the winter, so make sure you grab your jackets!
