I lived in Michigan for 18 years and rode horses there pretty much the whole time. I lived in Midland which isn't to far from Bad Axe. If you are looking for competitions and horse shows the Midland County Fairgrounds puts on a lot of shows all throughout the year. Also the Saginaw Fairgrounds puts on some. As far as trail riding there are trails EVERYWHERE across the state. There is a club in that area called Tri County Horse Association, they do a lot of trail rides and put on some shows. They would be good to get involved with if you are looking to trail ride. Also there is the Shore to Shore group, they do a ride every year either from East to West or North to South. There are horse camps that they stop at all along the state. You could look them up online on the Shore to Shore website or the MI DNR website. Some of the goods ones were Goose Creek, South Branch, Johnson's Crossing. All of them have sand trails and are pretty rider friendly. I will do some more research and see what I can find. If you have any more questions feel free to ask! Hope this helps!
