Fontainebleau Beach Pier

Mandeville, Louisiana

Located in Fontainebleau State Park in Mandeville, Louisiana, this beach is one of the most beautiful in the Lake Pontchartrain basin. Fontainebleau State Park is surrounded on three sides by water: Lake Pontchartrain, Bayou Cane, and Bayou Castine. The park is 2,800 acres in size and was once the site of a sugar cane plantation and brickyard.

The wealthy Bernard de Marigny, founder of the nearby town of Mandeville, developed this area across Lake Pontchartrain from New Orleans as a sugar plantation until 1852. The crumbling brick ruins of the mill, built in 1829, remain today and can be seen as you drive through the park.

The park has cabin rentals and RV access, miles of hiking and nature trails, picnic and playground areas, and the beach and fishing pier. An old railroad track that runs through the park has been converted into the Tammany Trace as a part of the Rails to Trails program. It is a wonderful route for cycling, hiking and in-line skating. The miles of nature trail are perfect for bird watching, with some 400 species frequenting the park.

It is accessible all year long through the State Park, which requires admission.

COVID-19

Keep your distance from other people.

Practicing social distancing is still essential. Only go to the beach if you are able to keep 6 feet or 2 meters away from others. Follow the instructions provided by your local health authorities. If your community has asked that you remain indoors and away from others, do so. Spending a day in any crowded place is the worst thing we can do for our most vulnerable right now and will counter our efforts to curb the virus’s spread.

Source Information

The Pontchartrain Conservancy (PC) monitors water quality at sites in the Lake Pontchartrain region. Sampling is conducted year-round, and samples are usually collected on Tuesdays and reported to Swimguide on Fridays. In the event of severe weather or holiday, samples may be collected on Wednesdays. Samples are not collected for the week of Christmas nor Mardi Gras.

Water samples are analyzed at all sites for Fecal coliform and Enterococcus. Water physiochemical parameters are also collected as field measurements. These include: Dissolved Oxygen (DO), water temperature, conductivity, and salinity (parts per thousand). Full weekly results can be viewed at: https://scienceforourcoast.org/pc-programs/water-quality/weekly-data-report/

A location will be marked Green when the average Enterococci in sample does not exceed 35 colonies/100 mL and no more than 10 percent of the individual samples collected shall exceed 130 enterococci colonies/100 mL; AND no more than 25 percent of the total samples collected exceed a fecal coliform density of 2,000/100 mL

A location will be marked Red when the average Enterococci in a sample exceeds 35 colonies/100 mL or 10 percent of the individual samples in the data set exceed 130 enterococci colonies/100 mL; AND if the location exceeds a fecal coliform density of 2,000/100 mL.

A location is marked Grey when there are no current results or there is no available information.
