This historic site is located along the concrete seawall where Bayou St. John meets Lake Pontchartrain in New Orleans. Originally an active Military Fort, built in 1779, to protect the city from invasion via the Lake, this area later became an entertainment district filled with amusement parks, restaurants, camps, and jazz. The name "Swim Hole" is a reference used by many area triathletes, that will meet up at the location for Wednesday night swimming and weekend races. The beach features parking on the other side of the levee as well as a small playground and a well-lit walk, run, and bike path right along the lake's edge. It's the perfect location to relax and enjoy the sunset on Lake Pontchartrain!
