I found the best map online and had it shipped to me before the trip, you might want that!
If you are not planning on driving the route first and making drop spots with water and food and such, you better plan on carrying alot with you. I don’t remember any potable water along the way.
If there has been any recent rain or any chance of rain RESCHEDULE!! Some areas of the trail are impassable when wet…(the trail turned to clay with a light rain and clogged up my gears, snapping off my rear derailleur)
Plan out your camping spots well, you don’t want to be scrambling for shelter in the dark!
Good luck!!
btw…the descent into Moab is still one of my favorite memories on a bike!!!
