Have ridden the Arapeen system 2 different times.
Those are great trails with lots of great overlooks and places to go.
We where there in 2018. Stayed in Manti, Great place to trail head out of.
We got snowed out the last day of riding during the 3rd week of September.
Weather is funny that time of year.
We also had a 147mile day.....that's a haul.
