I visit Scottsdale frequently to spend time with family. The first thing I want to do when I get off the plane is hike Pinnacle Peak. I don't care if it's 112 degrees in August, I'm doing it! This is a great workout if you're up for trail running or even just walking--I'd probably leave friends/relatives with heart conditions at home, however, as it's not quite an easy hike for those not accustomed to a steady climb. I love this trail so much that after I broke my ankle running it, I made it the first thing I did the next time I visited. THAT'S LOVE, DAMN IT... or maybe just insanity.
