This park almost demands that you lace up your hikers and get out of the car but if that isn't possible, it has 18 miles (one-way) of paved road along some impressive formations you can see from your windows. There are also some short, easy walks to viewpoints that almost anyone can manage.
Viewpoints accessible to strollers and wheelchairs:
Delicate Arch (lower)
Wolfe Ranch Cabin/petroglyphs (near Delicate Arch viewpoint)
The landscape from behind the windshield is impressive practically anywhere but some of the best formations are:
Tower of Babel
You will receive a park map with your entrance fee that marks where all of these are located. Do try and do your viewing from frequent pullouts and NOT by slowing to a crawl for photo-ops from your window. This route can be very busy so holding up tour buses and hikers making tracks to trailheads won't make you any friends, and could get you rear-ended. If intent on puttering, kindly use the pullouts to let speedier traffic by. Pay close attention to the cars in front of you: some other scenery gazer could make an abrupt stop that won't do your bumper any good at all if you're distracted!
There is an 18 mile long auto route with several stops along the way, some of which have very nice viewpoints. Although many of the views involve little or no walking, some hiking is required to really get a flavor for the park and to see the formations closer up.
Probably my favorite arch. Follow the main road and turn right at the first intersection. Easy access, you have to walk 10 to 15 minutes
