Thurston Peak (9,706 ft) straddles the Davis-Morgan county line, making it the tallest peak for both counties. Many people think that Francis Peak, with the big white golf ball domes on the summit, is the highest peak along the ridge, but it is Thurston Peak that claims the high point.
Donut Falls, located in Big Cottonwood Canyon, is a classic Wasatch Mountain hike. This hike is suitable for all hikers regardless of age or hiking experience. This is usually the trail I will take family that is visiting from out of state since it hardly gains any elevation, yet it leads to a beautiful destination. It is a very rewarding for those who don't regularly hike but still want to see Utah's varying scenery. Because of these things, Donut Falls is very popular - you will literally see hundreds of people here on weekends, especially in Summer. Hiking the Donut Falls trail is safe and easy to access year-round. Arrive early to beat the crowds.
