State Park · Louisiana
Louisiana's most-visited state park, on the north shore of Lake Pontchartrain near Mandeville: a sandy swimming beach, the brick ruins of an 1829 sugar mill under live oaks, birding trails, cabins, and a large campground that connects straight to the 31-mile Tammany Trace.
Field briefing
Fontainebleau State Park changes fast with season and elevation.
Before you go
The big draws are a year-round Lake Pontchartrain beach, the photogenic 1829 sugar mill ruins under live oaks, and direct access to the 31-mile Tammany Trace rail-trail. Plan around heat, humidity, and bugs in summer, bring a bike to get the most out of the Trace, and treat the campground or a cabin as the way to turn a day trip from New Orleans into a relaxed north-shore weekend.

Weather, crowds, and what the season changes about the trip.
Warm, breezy, and excellent for birding as migrants move through, with comfortable beach days.
Pack Sun protection, bug spray, binoculars, and a bike for the Tammany Trace.
Hot, humid, and busy, best for early beach time and shaded oak trails before afternoon storms.
Pack Water, sun protection, insect repellent, and a plan to be off the water by midday.
Cooling, pleasant, and quieter after Labor Day, with strong fall birding.
Pack Light layers, rain shell for passing fronts, and binoculars.
Mild and quiet, with cool, clear days good for walking and wildlife.
Pack Warm layer, rain protection, and footwear for damp trails.
Sugar mill ruins and live oaks
The park's signature landmark: the crumbling brick ruins of an 1829 sugar mill built by Bernard de Marigny, set among towering live oaks near the lakeshore. A short, flat walk and the best photo stop in the park.
Lake Pontchartrain beach
A sandy swimming beach on the north shore, open year-round, with a splash pad and playground nearby. The easy summer payoff and the reason many families come.
Tammany Trace and nature trails
The 31-mile rail-to-trail Tammany Trace crosses the park road near the entrance, linking to Mandeville and Covington, while the park's own birding trails wind through marsh and forest.
Move exposed miles to the morning and keep water, shade, and storm checks ahead of the wish list. For one day in Fontainebleau State Park, make Sugar mill ruins and live oaks the non-negotiable, add Lake Pontchartrain beach only if the first stop runs clean, and keep Tammany Trace and nature trails as the flexible finish.

Camp or book a cabin in the park to anchor a north-shore weekend, since the large campground sits close to the beach, the trails, and the Tammany Trace. The deluxe cabins reopened recently and suit families of up to eight. Mandeville and Covington are a short ride away on the Trace itself and offer the nearest restaurants, while New Orleans is close enough that many people day-trip across the causeway instead of staying over.
Camping reservations
Fontainebleau is Louisiana's most-visited state park, so summer and holiday weekends at the 143-site campground and the cabins fill ahead. Decide between a campsite and a cabin first, then lock the date.

Getting there
Arrival note
Fontainebleau sits on the north shore of Lake Pontchartrain just east of Mandeville, about 40 miles from New Orleans across the Lake Pontchartrain Causeway.
Car strategy
A car is the practical way in, though once you arrive a bike unlocks the Tammany Trace and the towns of Mandeville and Covington without driving again.
Pair this with lodging: the useful base is the one that connects cleanly to how you actually arrive.
Yes. The park has a sandy swimming beach on the north shore of Lake Pontchartrain that is open year-round, along with a splash pad and playground that make it a popular family destination. Check the park's current conditions for water-quality advisories before counting on a swim.
The Tammany Trace is a 31-mile paved rail-to-trail path for walking, biking, and skating that crosses the park road near the entrance. From the park you can ride directly to Mandeville and Covington, which makes a bike one of the most useful things to bring.
Yes. The park's deluxe cabins recently reopened and suit families of up to eight, alongside a 143-site campground with tent and RV sites. Both book up on summer and holiday weekends, so reserve early through the Louisiana State Parks system.
