This is located in Phoenix by Lincoln Road and 24th. It's about 1.2 miles to the top so you can get up and back within an hour.
It's fairly easy - if you are used to doing stairs as you'll basically be climbing up a lot of them.
When you get to the top, there are great views of the city below. The only thing you'll need to watch out for are people who are racing up and have no intension of stopping to let you get out of the way.
If you hate stairs, try the circumference trial instead. Yeah, the name is totally not creative, but it's much easier than the stair one (even kids can do it) and you still get to see the city from way up high.
Level: Easy to Moderate
