Schnebley Hill is named for Sedona Schnebley who Sedona is named after. The road connects Sedona to 1-17. While this review is (primarily) about the vista) I highly recommend taking the full tour of the road. Start at I-17, Schnebley Hill Road. You begin with beautiful national forest, high desert grassland, and quiet ranches, then you approach the red rocks, and the road gets QUITE rough (HIGH CLEARANCE) but the views get more and more spectacular. The high pines, high desert grasslands, then the red rocks, makes this an unforgettable trip.
Again high clearance is a must, this is not a trip for someone who cannot take bumpy roads.
