We started at the left side of the loop. scenic veiws and in the valley soon after we started. at our end which is the right of the loop its alot of down hill, but not to steep so if you want a good work out from the start, start with the right side first. the whole loop is 3.2 or 3.4 the 6 miles is if you include to go down to Dewey lake. which we didnt due to alot of smoke in the air. it was just time to be done. August 18 2018 if Dewey lake is your main destination start with the right side of the trail loop youll get there faster.
hope this helps!
