Whenever I visit Moab Sand Flats is the first place we choose to camp. We choose this spot for a few different reasons: 1) My husband is an avid off roader/Jeep rock crawler and you are 5 minutes away from two popular and fun trails, 2) It is a big enough area where you can find spots close to people and be social or you can find spots that are a little more isolated, 3) the view is amazing, 4) besides Jeeping, hiking and mountain biking are right there. Depending on what time of year you can get any weather. I have had snow as well as heat in April. Because you are in the desert, the more into summer you get, the hotter the weather so be sure to have lots of water available. Finally, the cost is affordable and parking/roads are easy to navigate. Because you are near off road trails, there is a fair amount of car noise during the day. At night people are pretty respectful and unless you are camping right of the trail (specifically Fins N' Things) where people will drive at night, I don't really notice it. There are open toilets (no roof but walls) which is nice but showers are in Moab.
