For such a laid-back objective, the best things to do in san diego could amaze you. As the country's eighth-biggest city, San Diego isn't the lethargic ocean side town many once considered Los Angeles' laidback neighbor-while there's still a lot of surfers and Navy service members to be seen here, the waterfront city is a worldwide super locale extending from Imperial Beach to Oceanside. Come here for the sea shores, sure, yet remain for the way of life.
