Lake Pontchartain is pretty large at approximately 30x40 miles. To get technical it’s actually an estuary that opens to the Gulf of Mexico. It’s interesting because you can find both saltwater and freshwater fish in it. We also saw a few mallards swimming when we were there. I always like to check out marinas too. Although the Marina in Metairie was undergoing construction so we didn’t get to see much. Metarie is a suburb of New Orleans that is worth checking out if you need a break from New Orleans or want to try a less busy and less touristy restaurant with authentic New Orleans cuisine.
