Moab is a small town, so walking and biking are great options for short distances. For the national parks and state park, a car is necessary. Be sure to fill up the tank before heading out for the day. Gas prices tend to be higher in Moab. Parking is available at each park entrance. The rafting company provides shuttle service to and from the river.
If you have more time, consider adding a hike to the Devil's Garden Trail or a drive on Potash-Lower Colorado River Scenic Byway. If you have less time, consider skipping a national park and spending more time at the others.
