As the name gives away, this is also not a trail for the faint of heart. For those of you that consider you hardcore offroaders, the Upper Helldorado will truly put your skills to the test. We might even dare to say it is the most challenging trail in all of Moab. It may be only a quarter mile trail, but don’t let this fool you. The time to run this trail can vary from a half hour (if you’re lucky) up to three days (if you’re unlucky) depending on your equipment and skills.
