There are there are 5 different loops. The longest being .6 miles. The elevation change is pretty moderate though. 2150 ft at the base of that trail to 2900 ft at the very top of another. There are plenty of choices in the middle though.
Honestly it depends on how many trails you take. There's three or four trails that loop and connect together. They're all pretty short, less than a mile. I did one loop trail with my dog at a leisurely pace and it took about half an hour.
Depends on which loop you take. One is not terribly long, but it can get quite steep.
