FUN!The Federal Highway Administration considers this road to be the curviest road in the nation, with 450 switchbacks and up to 1000 curves and turns in total. The rumors on the rider grapevine are true. For an incredible ride, this one is very hard to beat. It’s long, it’s twisty, it’s a roller coaster, and it’s in a wilderness setting that will thrill whatever senses you have left that the road didn’t overload. The elevation change is more than 6,000 ft from around 3,000 ft in the Sonoran Desert to over 9,000 ft in the Alpine meadows, forests and highlands.
