Saint Bernard Parish: See
Chalmette. St. Bernard's largest city also includes the site of the "Battle of New Orleans" from the "War of 1812" and the ruins of the De la Ronde Plantation. Other than these historic sites there is little to "sight see" in mostly modern Chalmette, but it is the Parish's center of commerce and dining. Details in the Chalmette article.
Terre aux Bouefs region. Highways 46 and 300 wind into the eastern part of the Parish historically known as the "land of oxen" or "Terre aux Bouefs". The two highways run roughly parallel through the region from the town of Poydras on the Riverfront to the area around the village of Regio to the east, with small roads and streets linking the two highways. A series of small communities dot the routes. 46 is the quicker more modern highway, but 300 aka Bayou Road is more scenic with pretty bayou views and historic sites, including the old St. Bernard Church and Cemetery , Kenilworth Plantation House, and the Isleño Cultural Center. As of 2012 a bridge on 300 is out at the town of Toca, where you have to drive half a mile over to 46 and then back again on the other side-- the historic scenery on the old road is worth taking this route despite the detour.
Delacroix Island Some think it is debatable as to if the town of Delacroix is actually an "island"; it's an inland town in an area surrounded by swamps and bayous. It was only accessible by boat until the 1930s when the WPA built a long road through the wetlands to here; it's at the far end highway 300 south of Regio. Sometimes called "the end of the world". Though almost wiped out by Katrina, the long famous fishing community of Delacroix is back.
Shell Beach is a fishing and boating community at the end of Highway 46. If you go out on a boat from here, try to swing by the ruins of historic old Fort Proctor, no longer accessible from land.
