Sitting at the base of the Golden Gate Bridge, this indoor-outdoor museum offers entertaining and enlightening hands-on exhibits for children under eight. Kids can fish from a boat at the indoor wharf, imagine themselves as marine biologists in the Wave Workshop, and play outdoors at Lookout Cove (made up of scaled-down sea caves, tidal pools, and even a re-created shipwreck). At Tot Spot, toddlers and preschoolers dress up in animal costumes and crawl through miniature
tunnels. From San Francisco, take U.S. 101's Alexander Avenue exit and follow signs to East Fort Baker.
