Fort Drum Marsh Conservation Campground offers primitive camping at three designated sites within a 20,862-acre conservation area in southwestern Indian River County, with two sites requiring hiking access and one group site near Horseshoe Lake with vehicular access.

The area features a wooden boardwalk through hardwood swamp to Hog Island, 5 miles of trails for hiking, paddling opportunities on Lake Cara and Horseshoe Lake, fishing year-round, and horseback riding on designated trails.

Advance reservations are required for camping, and the best visiting conditions are during the dry season when trails are more accessible.
