Start early, while the day is still cool, with a 3-mi round-trip hike on the Delicate Arch Trail . The route is strenuous but richly rewarding. Pause for a healthy snack before heading for Landscape Arch, the second of the park's two must-see arches. To get there you must hike through Devils Garden, a great spot for morning photography. If you're accustomed to hiking you might next hike out to Double O, a trip that is well worth the effort but that can be tough after the hike to Delicate Arch—especially in July or August. If you do hike to Double O, take your lunch with you and have a picnic in the shade of a juniper or in a rock alcove. Don't forget to pack out every scrap of paper and food. By the time you return you'll be ready to see the rest of the park by car, with some short strolls on easy paths.
In the mid- to late afternoon, drive to Balanced Rock for photos, then on to The Windows. Wander around on the easy gravel paths for more great photo ops. Depending on what time the sun is due to set, go into town for dinner before or after you drive out to Delicate Arch or the Fiery Furnace and watch the sun set the rocks on fire.
