Red rock crossing is the classic area, very nice, it's a State park, and costs a few dollars to get in. The Vilage of Oak Creek has Cathedral rock and other buttes, and go up airport road, there is a pull off just before the Sedona airport, great views. BTW, the forest service now charges $5 a day to park just about anywhere scenic in the Sedona area, purchase permit at any gas station or mini-mart. Boyinton canyon is nice, but about a 6 mile hike, round trip, kind of hilly, gets real steep at the end, and takes at least 4 hours, more if you stop to take photos. It took me 6 hours, but I stopped a lot. Sedona is VERY crowded on weekends, and traffic is bad, so plan accordingly. March is an excellent time of year in Sedona, much better than summer.
