The River Walk, San Antonio, Texas

San Antonio is a rare breed of city that is built not around its river, but specifically around its River Walk—a city park that stretches for five miles along the San Antonio River. Strolling it is the best way to sample the city. Start at the San Antonio Museum of Art (200 W. Jones Ave.; 212-978-8100; samuseum.org)—be sure to check out the survey of American photography, on display through August 19—and then continue toward La Villita, a historic arts village filled with galleries, studios and artisans. End the day with the tasting menu at Biga on the Banks (203 S. St. Mary’s at Market; 210-225-0722; biga.com)—ask for table 31.
