In response to hoopy's reply:
Your criteria is tough.... as where there are views there's generally little water and the "loop" part adds another dimension; but here goes.
If you enjoy swimming pools and hiking in a canyon, you might consider the West Fork of Oak Creek. If you go, you will need waterproof packs if you go upstream past the +/-8 mile point as there a few mandatory swims. This, however, is an "out-and-back" hike.
For something less aggressive, you might consider heading to
Taylor Cabin on the Dogie Trail and returning along Casner. This could be "toasty" depending on when you plan to hike it. But there should be water in the creekbed 1/8 mile south of the cabin.
Another consideration might be heading up the
Hot Loop and returning via the
Jack's Canyon
You should call the USFS for an updated water report on this area. (try to get a "field" guy/gal - not just an office staffer)
You could, as well, drive up Schnebly Hill Rd. (FR 153) and set a water/food cache. That way you be assured water.
NOTE: If there is any way that you can arrange a shuttle, it opens up your choices immensely.
Have fun and be safe!
Further personal editorial: The frou-frou Sedonaites have disallowed camping in "their" National Forest. They'd rather that you camp in the (always full & wall-to-wall) USFS campgrounds. "Oh, but be sure that you buy our "Red Rock Pass"" (same as Adventure Pass in Ca.) "We'll take your money, but don't dare camp in our forests."
At the remote trailheads you generally would not run into enforcement of the "no camping" edict if you were to arrive late, however.
