The long, sandy shore comprising Pacific, Mission and Ocean beaches offers mediocre surf, but because of its close proximity and easy access for the majority of San Diego's population, surfers manage to make the most of it. Like all the other popular beaches in town, lifeguards divide swimmers from surfers in the busy summer months, and it's important to make sure you're where you belong. What the surf itself lacks, the beach scene more than makes up for, and the P.B. - M.B. boardwalk is always bustling with activity. For something totally out of the ordinary, check out the Wave House at Belmont Park, an artificial wave that allows you to ride perpetually without setting foot off the shore.
