Fontainebleau State Park
A Lake Pontchartrain beach, pier, marsh, live oaks, trails, and brick sugar-mill ruins layer recreation over plantation and industrial history.

Artwork inspired by Clarence Millet
Fontainebleau occupies part of Bernard de Marigny de Mandeville’s former sugar plantation. Brick ruins, old live oaks, shoreline, and nearby rail-trail connections allow visitors to link plantation production and enslaved labor to later logging, resort development, conservation, and recreation instead of treating the park as only a beach.
Lake conditions decide the day. Wind can roughen shallow water, high bacteria readings or storm damage can close swimming, and intense sun reaches the pier and beach. Walk the ruins and nature trail before settling at the shore, read current advisories, and remember that Lake Pontchartrain is a brackish estuary connected to the Gulf rather than a freshwater lake.

Quick guide
- First
- Ruins + nature trail
- Then
- Pier or beach if open
Make the visit count
- Read the ruins
- Connect brick foundations to sugar processing, fuel, transport, and enslaved labor.
- Check the water
- Use posted swim advisories and wind conditions, not visual appearance alone.
- Watch the marsh edge
- Look for scan for herons, rails, crabs, and changing salinity indicators.
- Extend by bike
- The Tammany Trace passes nearby, but confirm the safe connector rather than riding highway shoulders
Good to know
Beach and pier access can close independently after storms, water-quality alerts, or repairs. Shade drops sharply near the lake, and cabins or campsites book far ahead; verify the exact amenity you want instead of assuming that an open park means swimming, rentals, and every trail are available.
