With so many calm, protected bays, plus an array of exciting sea caves, it’s no wonder that San Diego  boasts some of the best sea kayaking in the state. Whether you’ve got your own boat or you plan to rent or take a tour, the most popular spot to paddle are the La Jolla Caves, part of the larger La Jolla Cove Ecological Reserve (1100 Coast Blvd., www.sandiego.gov ).
Scuba San Diego (619/260-1880, www.scubasandiego.com ) offers guided paddles of this well-traveled area. You don’t need any previous sea kayaking experience to take this easy two-hour tour; the sit-on-top kayaks are easy to get into and out of, and safe if you happen to fall off.
On the tour, you’ll visit soaring sea cliffs and a vast kelp forest, and paddle through the famed local sea caves.
