Green Valley is a municipal golf course on the south side of Sioux City off I-29 at Singing Hills.

The golf course is a parkland layout with trees scattering the rolling fairways along multiple ponds, lakes, and streams and a modest amount of sand traps. It's entertaining with a variety of interesting holes, especially the par 3s and a few of the par 5s which may be reachable in two providing ample scoring opportunities. It was designed by David Gill in the 1960s and from the tips can play to 7,085 yards,74.0/123, course/slope ratings with three shorter tees.
