Fontainebleau State Park
🦢 Trusted Guide to Louisiana’s Lakeside Treasure – Updated 2025
Where Bayou Country Meets Lake Pontchartrain
Spread across 2,800 acres along the northern shore of Lake Pontchartrain in Mandeville, St. Tammany Parish, Fontainebleau State Park blends Louisiana’s plantation history with exceptional natural beauty. The park takes its name from the French royal palace — a fitting comparison for these grounds, which once served as Bernard de Marigny de Mandeville’s sugar plantation in the early 1800s. Today, the crumbling brick ruins of his 1829 sugar mill stand as atmospheric reminders of antebellum Louisiana, while over 400 bird species, miles of trails, and a sandy Lake Pontchartrain beach make this one of the most diverse state parks in the Gulf South.
Sugar Mill Ruins & History
The atmospheric brick sugar mill ruins date to 1829 and represent one of the most photogenic historic sites in Louisiana’s state park system. Built by Mandeville himself — the town’s founder and one of New Orleans’ most colorful characters — the ruins stand draped in Spanish moss beneath live oaks. Interpretive signage explains the plantation’s history and the sugar production process that once drove this region’s economy.
A Birder’s Paradise
Fontainebleau’s position between Lake Pontchartrain, Bayou Cane, and Bayou Castine creates intersecting habitats that support over 400 species of birds and other animals. Spring and fall migrations bring spectacular concentrations of warblers, tanagers, and shorebirds. Year-round residents include herons, egrets, ospreys, and woodpeckers. The park is a recognized birding hotspot that draws enthusiasts from across the Gulf Coast.
Trails & Tammany Trace
A 1.25-mile nature trail with interpretive signs winds through the park’s pine flatwoods and hardwood hammocks, while a 4.8-mile hiking trail extends to Bayou Cane through more remote forest. The park also connects to the Tammany Trace, a converted rail-trail popular with cyclists and joggers that stretches 31 miles across St. Tammany Parish — one of the best paved recreational trails in Louisiana.
Beach & Water Activities
The park’s sandy Lake Pontchartrain beach offers swimming and relaxing against a broad lake horizon. Kayak rentals provide access to quiet bayou paddling through cypress-tupelo swamps teeming with wildlife. The lake’s gentle waves and shallow waters make this a family-friendly waterfront experience.
Camping & Lodging
Choose from 96 premium campsites with full hookups, 37 unimproved sites, primitive group camping areas, 12 deluxe cabins, and a lodge — accommodations ranging from rustic to comfortable. The campground’s live oak canopy provides welcome shade in Louisiana’s warm months.
