If you're camping at Fleming Park the closest course is Wilber Young Disc Golf Course at Blue Springs South High School. However, I don't know that it is the best course on the Missouri side although it is certainly challenging and a fun course. Most people will tell you to play WaterWorks which is just north of downtown KC. It has been and probably always will be the best known course in the metro. I'll let the guys from the West side comment on what course to play in KS.
