Best route, IMO, is from Brighton, up past Mary, Martha, and Catherine, then head west to the Wolverine Cirque, back down past Lake Solitude, and back to the car.

Catherine from Alta is good as well, but more sun exposure and traffic. Run from Alta to Twin Lakes Pass, over into the Mary/Martha/Catherine Basin, and back down to the car from Catherine Pass.

There are other great options up there — that's some of the best terrain in Utah, IMO. And depending on the time of year, the flowers are excellent
