Sea Grove Park is a great place to start but if you head towards the ocean, you can't go wrong! All of the beaches here are great. For the dog lovers, there's always Del Mar Dog Beach
Check out any of these great trails: Torrey Pines State Natural Reserve, Crest Canyon, Scripps Bluff Preserve, San Dieguito Lagoon, Riverpath Del Mar and San Elijo Lagoon
Either schedule a lesson or rent some gear for a surf day.
Balboa Park is the cultural heart of San Diego, a 1,200 acre wonderland with fifteen museums, eight gardens, and the world-famous San Diego Zoo. Often referred to as the “Smithsonian of the West,” it is the largest urban park in North America, exceeding even New York’s Central Park in size. It will take more than one day to see and enjoy it all.
