Bangert Island

Bangert Island

This 160 acre park is between the Katy Trail and the Missouri River just south of downtown St. Charles. 4.2 miles of singletrack, with some sandy areas, have been squeezed onto the island. The main loop is a figure 8 designed to be accessible to the beginning rider with minimal elevation change. The Sandy Loop weaves in and out of the drainage troughs alongside the river edge, offering a change of pace from the flats on the main loops. 

The trail is subject to seasonal flooding, and once the river level reaches 23', the bridge is no longer accessible.


Take I-70 to the 5th Street exit in St. Charles, and head South on 5th Street. Bear left onto the South River Road, and then left again onto Old South River Road. Parking is available on both sides of Old South River Road.  


Water, food, and restrooms are available in downtown St. Charles, approximately one mile north on the Katy Trail.  


An island in the Missouri River just south of the Blanchette Bridge, the Louis H. Bangert Memorial Wildlife Area (Bangert Island) was a partnership between the Missouri Department of Conservation and the St. Charles County Parks Department. Under the agreement, the MDC owns the property - following a 1976 donation by Anna Louise Kurtz and Edwin Kurtz to honor Anna's father Louis H. Bangert - and the Parks Department will manage the park through a 30-year, renewable lease.  2016 update: St. Charles City has purchased the land comprised of Bangert Island.

Outer trails are good. Avoid the center connector on the Slough Loop, still slimy.

The trailhead says "open" but bikes should stay away. Corners, kickers, and obstacles are wet and dangerous. Risk of trail damage isn't worth it. Should be fine Sunday or Monday.

Wet and slippery. Lots of wet mud.

Tree down on Slough Loop just around the bend from River Link, will likely need chainsaw. Trail surface dry as a bone.
