Fox River Bluff straddles the Fox River in St. Charles. The portion on Route 31, along the west shoreline of the Fox River, is known as Fox River Bluff West Forest Preserve.
Among the first things you'll notice at this popular preserve are dogs. This preserve is one of the District's approved off-leash dog areas. Owners are welcome to walk (or run!) up to three dogs at one time here. We ask owners to kindly keep dogs on leash while walking to/from vehicles, and while crossing the bicycle bridge over the Fox River. A full list of Rules & Regulations for use of the Off-Leash Dog Area is available here.
Pedestrians and bicyclists also use this preserve to traverse the Fox River and connect with the Fox River Trail, on the east side of the river, which runs through Fox River Bluff (East) Forest Preserve.
