Staying In Archers Nat. Park in July?

OP - Yes, it will be hot in Arches. But the desert does usually cool off nicely at night. Do you have A/C on your unit? If so, might it make sense to buy a generator, perhaps sharing it with your trip mates. Then, when you return from your day trips, you can start the genny and a/c and at least get the trailer cooled down some. Also, site selection is important. Site 48 get pretty good shade in the afternoon from the rocks. Site 46 less so, but still better than most of the sites on the east side of the road. But whatever you do, it will probably be pretty warm. The CG at Arches is one of the most scenic NPS CG's around, so you have to decide whether the experience is worth the heat. Dead Horse Point SP is quite nice, but pretty removed from Moab and Arches. But the electricity is nice if you have A/C.

ekirkland - Early May is getting right near the time it starts to get quite warm. Most years, it's totally tolerable then, but there can be exceptions.
