Masaya Volcano

Volcano Masaya's crater once stretched more than 3 miles, a piece of geological history you can see standing on top and gazing out over the hardened lava field. Over time, other eruptions began to fill it in. Now, you can hike over a ridge and see another crater, where trees have bloomed and blossomed. The main crater is a massive cauldron of sulphur, dancing up into the sky and sometimes coating your lungs when the breeze is right.
It is massive.
One hundred and seventy five steps gets you a view of the entire crater and the landscape beyond, and a look up at a very large cross. It commemorates the Spanish, who came here and believed the crater was a gateway to hell when they bore witness to it.
There is a chain of volcanoes in Nicaragua, all visible to us most of the time.
