Spanning nearly 5,000 acres between US 1 and the South Fork of the St. Lucie River, what is now Atlantic Ridge Preserve State Park was once a cattle ranch.
It is now well hidden by surrounding subdivisions. You won’t find road signs to guide you to this state park in Stuart, and you need a gate code to get in.

About the Park
Managed by nearby Jonathan Dickinson State Park, this low-key day-use preserve protects upland and floodplain habitats along the waterway.
While a network of nearly 30 miles of marked ranch roads is popular with equestrians, we found it tricky for off-road biking due to stretches of soft sand and grass.

Footbridge over a tributaryBlaze colors and markings differ along the route, which hovers close enough to the river we’re calling the full series of loops the River Hammock Trail.
Spur trails lead to scenic overlooks. Footpaths weave deftly down narrow passages through tall saw palmetto and tropical hammocks.
Narrow trail through a tropical hammockBridges cross narrow but deep drainages in healthy pine flatwoods, and intersections are presently marked with “Trail” and “Exit” signs.
Utilizing one of the ranch roads, River Road, as a backbone for the loops, the marked trails tallied close to five miles of hiking.
