Everyone has to hike to Delicate Arch at least once. To make the most of the experience, try to go on a weekday when the crowds are thinner.
Next, The Whole Enchilada is one of the highest-acclaimed mountain bike trails in the world! If you're a rider, you have to hop on a shuttle and shred as much of this epic route as the snow levels will allow.
Dead Horse Point is one of the most photographed scenic vistas in the world, so you better go get a snap for the 'Gram, huh?
Finally, cap your must-do experience with a visit to the Slickrock Trail. Whether you bike, hike, run, or even dirt bike or 4x4 (not on the Slickrock trail, but on other nearby trails that intersect with it), the bald rock domes in this area create an otherworldly landscape that you have to experience first-hand.
