Castlewood State Park
Castlewood State Park: Bluffs, Ruins, and River Magic Minutes from St. Louis
Just 20 minutes from downtown St. Louis, the Meramec River carves through a landscape of white limestone bluffs, abandoned resort ruins, and 1,800 acres of forest that feel a world away from the city. This is Castlewood State Park, where you can stand on a 100-foot bluff watching the river bend below, explore the crumbling foundations of a forgotten 1920s resort town called Lincoln Beach, and mountain bike some of the best singletrack in Missouri — all before lunch.
Castlewood is proof that great state parks don’t need to be remote to be remarkable. The park’s dramatic bluffs overlooking the Meramec, its layered human history, and its 18+ miles of trails for hiking, biking, and horseback riding make it one of the St. Louis metro area’s most treasured natural spaces.

The Bluffs
Castlewood’s white limestone bluffs rise approximately 100 feet above the Meramec River, offering some of the most dramatic viewpoints in the St. Louis metro area. The River Scene Trail climbs to the bluff top, where you look down on the river bending through thick bottomland forest. In autumn, the bluffs are framed by brilliant fall foliage. In spring, the river runs high and fast after Ozark snowmelt.
Lincoln Beach Ruins: A Lost Resort Town
In the early 1900s, a resort town called Lincoln Beach thrived along the Meramec River at what is now Castlewood. Hotels, dance halls, a swimming pool, and a grand riverfront promenade drew St. Louisans seeking weekend escapes. But repeated flooding and the Great Depression killed the resort, and the buildings were gradually abandoned and reclaimed by the forest.
Today, hikers can still find concrete foundations, staircase remnants, and building footprints scattered through the woods along the river — ghostly traces of a vanished era. It’s one of Missouri’s most atmospheric hiking experiences, combining nature and history in a way few state parks achieve.
