There are LOTS of campgrounds around Moab. Portal Ranch actually has it's own website, and that is central campground and start of all runs. Lots of people camp in Moab. I would rather bring my own coffee maker, and stay where there is a hot shower, and wake up calls. The Super 8 is a few hundred feet away from Portal, and the Motel 6 is closer still. Portal Ranch has cabins at resonable rates, tent spaces, and trailor spots. It has dog runs, running water, and hot showers. If you are interested in getting a cabin, or reserving a tent space, it's limited and I would make reservations as soon as possible.
Anxiously waiting and counting down Moab,
