Derived from the Mayan for “large hill,” Nohoch Mul is by far the largest (and to judge from pictures online, the most-photographed) structure at the Maya ruins of Cobá:

As you can see, parts of it (on the sides of the stairway) are in rough shape — but it’s got the advantage of being one of the largest Maya pyramids that visitors are still allowed to climb. And for those with issues with heights, a rope is provided to help you get up and down.

The view from the top is pretty impressive, too!
