Clocking in at 630 square miles, massive Lake Pontchartrain (p. 61) isn’t really a lake at all but a brackish estuary connected to the Gulf of Mexico. For generations the lake has served as a popular retreat for families as well as fishing and boating fans. Along with numerous green space and recreational areas, the lakeshore is home to the nation’s second-oldest yacht club, the art deco Lakefront Airport (where Amelia Earhart stopped en route to her final flight) and seafood-centric restaurants overlooking the Orleans Marina. The New Canal Lighthouse offers tours, as does the National WWII Museum aboard its recently renovated PT-305 boat. Lakeshore Landing, a new $12-million entertainment complex, is currently in the works. Get going! Explore the city at wheretraveler.com.
