Old Bulls Cutoff is a trail that is about a mile long and not much more than a well trodden game trail. Why should you care?
You should care because Old Bulls Cutoff connects the Continental Divide Trail with the Ruby and Butler Creek Trails. This one mile section of trail can be used to ride two loops along the CDT; a Ruby Creek Loop and a Stevenson Trail to May Creek Loop.
The 14.8 mile Ruby Creek Loop is best ridden clockwise from Big Hole Pass. There is about 4200' of climbing and descending.
Stevenson to May Creek Loop is about 20 miles and can be ridden from the May Creek Campground. Also 4200' of up and down.
These two loops are tough with all that climbing but you will have earned access to some beautiful high-country.
