Located approximately two miles east of Hwy. 30, in Grubville, MO. the Big River Saddle Park, is a unit of the Jefferson County Parks Department, and is also host to horse shows produced by  local organizations.

There is parking all around the show pen and many well shaded spots for early arrivals on show days. The arena is large, surrounded by chain link fence, but there is only a minimal, unfenced, practice area. A margin of grass around the pen is sufficient for lawn chair set up.

The facility is open to the public for general riding on days when there is no show. There are primitive restroom facilities. Riders are required to tether horses to trailers, rather than the many trees surrounding the parking areas.
