This loop has three sections and is less than 40 miles long.
1. Pleasant Canyon to Rogers Pass to Butte Overlook
2. Middle Park
3. South Park
Middle Park is by far the easiest section and is a high altitude valley.
South Park has Chicken Rock and Chicken Bridge, Briggs Cabin and a steep rocky canyon to the bottom.
If you can ride an adventure bike on this loop, you are a pro level rider as far as I am concerned. Even someone on a light weight dual sport bike should be an experienced rider. This loop is not for beginners. Again, in my opinion, it is always better to ride with someone else in case something unexpected happens.
