Mexico/Puebla: Cuexcomate

Cuexcomate is an extinct giant geyser, located in the suburbs of Puebla. It is mistakenly known as the world’s smallest volcano, which it is not. The geyser was formed thousands of years ago during one of the eruptions the nearby Popocatepetl volcano. The empty geyser come is 13m/43ft high above ground and 17m/56ft deep with a metal staircase spiraling down to the very bottom. The cave-like material is 99% calcite. It’s a small natural attraction that doesn’t require a lot of time to visit, but descending down and views from the bottom are an awesome experience.
