campsite Arches National Park Utah

Is that usually hard to get?

Arches is always packed like sardines. Yes, reservations are tight. Hot, noisy and tedious in my opinion. Much better to go down the road and climb onto the mesa towards Canyonlands IMO. No water but much better surroundings. Try the BLM campground called Horsethief, it's usually empty. Or get out into the open. Dead Horse SP is usually all reserved or occupied.

I go to Moab usually twice a year, the RV park across the road sort of from the Arches entrance pretty nice. Once there we ride our dirt bikes all over the place. You will see ATV and Side by sides driving down the streets there. There is so much to see there it is nice to have a base camp.
