Boxcar Bend is the westernmost boat access point on the Lake Red Rock Water Trail in Marion County, Iowa, serving as the starting point for paddlers exploring the scenic 12. 5-mile lake.

In low water conditions, the area is shallow (often only about a foot deep) with sandy shoals that may require portaging, making it best suited for kayaks and canoes rather than larger powerboats.

From this access point, paddlers can explore wooded areas, sandy beaches, and the dramatic South Shore Cliffs along the Des Moines River.
