What is there to do at Fontainebleau State Park?
Fontainebleau State Park mixes a lakefront beach, hiking, birding and plantation-era history in one stop. Water wraps the park on three sides: Lake Pontchartrain, Bayou Cane and Bayou Castine. Start at the lakefront, then hit a trail or the sugar mill ruins before lunch.

- Beach and pier. Fontainebleau State Park has a sandy beach with a pier reaching out over Lake Pontchartrain. Walk the pier late in the day; the sunsets over that open water are hard to beat.
- Hiking. The 4.8-mile hiking trail at Fontainebleau State Park is the big one, and a shorter nature trail suits little legs.
- Sugar mill ruins. Bernard de Marigny de Mandeville, who founded the town of Mandeville, ran a sugar operation here, and his sugar mill was built in 1829. Marigny named his land Fontainebleau after the forest near Paris.
- Birds and wildlife. According to Louisiana State Parks, more than 400 species live in and around Fontainebleau. Bring binoculars!
- Picnics and play. Fontainebleau State Park has a picnic area, a pavilion and a playground, so lunch is easy.
Folks across St. Tammany Parish love this place, and Visit The Northshore says it best: “Fontainebleau State Park in Mandeville is Louisiana’s most visited, and for good reason.”

The Mandeville Trailhead Market makes a good Saturday-morning warm-up before the state park. Afterward, the City of Mandeville’s lakefront park, about one mile in length, is a nice cool-down walk.
Can you bike the Tammany Trace into Fontainebleau right now?
Not from Mandeville this season. St. Tammany Parish closed Tammany Trace Bridge #13 over Bayou Castine, between Rapatel Street and Group Camp Road in Mandeville, from October 12, 2026 through May 2027 so crews can replace it. The parish says no detour is available around the Bridge #13 work.
St. Tammany Parish has paved 31 miles of the Tammany Trace along an old railroad line. Louisiana State Parks notes that the old railroad track through Fontainebleau State Park is now part of the Tammany Trace, so in a normal year you could pedal from Mandeville right into the park. For now, drive into Fontainebleau and ride or walk inside it instead. St. Tammany Parish also lists Tammany Trace Bridge #14, between Molitor Street and Dupre Street in Mandeville, as closed through early 2027, with a detour on Montgomery Street. Peek at the Tammany Trace closures page before you go, since bridge timelines can shift.
When should you visit Fontainebleau State Park?
Fall and early winter are the sweet spot for a Fontainebleau day trip. The NOAA 1991-2020 normals for the Slidell Airport station in St. Tammany Parish put the average October high at 80.5°F and the average November high at 71.0°F. That’s comfortable hiking weather, not sweat-through-your-shirt weather.
Mornings turn crisp, too. Slidell Airport’s average November low is 46.7°F in those same NOAA normals, so bring a layer if you’re catching sunrise on the pier. Summer still works for the beach, but plan to finish the trails before the afternoon heat sets in.
