Fodor's Expert Review Fiesta Island

The most undeveloped area of Mission Bay Park, this is popular with bird-watchers (there's a large protected nesting site for the California tern at the northern tip of the island) as well as with dog owners, because it's the only place in the park where pets can run free. Firepits are scattered across the island for public use. In July the annual Over-the-Line Tournament, a competition involving a unique local version of softball, attracts thousands of players and oglers.
