Years ago I took some mule guys and my kid on a ride to the Boulder Mountain in south eastern Utah. It a great place to ride. Scattered pine trees and quakies groves with numerous lake and not a lot of under growth. The Boulder is relatively flat on top at an elevation of about 1050 feet.
My oldest son, the only one of four who took to horses.
My favorite lake on the mountain is McGath Lake. When I want to impress my friends, we go to McGath.
I know the guy that runs those mules into Grand Canyon. So if you ever want me to line you up,, let me know. And any time you want to ride in southern Utah, I know some really good trails, and some that will make ya put nothing but toes in the stirrups.
