>>2206639If you are driving from CO to UT take the exit for rout 128 off 70 to Cisco. Its an abandoned town, then proceed on it all the way to Moab. Tons of amazing hikes, and scenery along the way. I had no issues sleeping in the car in some lots, and scenic pull outs.
Arches park can be packed, Canyonlands is just 45 mins further south and has far less people. Take the Shafer offroad trail back to Moab. you dont need 4x4, a regular car should do fine. again, amazing sights.
If you want to visit antelope canyon, you need to book in advance, it has shitty hours, and is on indian reservations so you cant just drive there. need to be in a group
