Landscape
This is an active volcano where you can get close enough to the lava flows to poke sticks in it. The ground is made up of loose volcanic rock and is quite unstable in parts.
History
Pacaya first erupted approximately 23,000 years ago and has erupted at least 23 times since the Spanish conquest of Guatemala. After being dormant for a century, it erupted violently in 1965 and has been erupting continuously since then, sometimes showering the nearby city of Antigua with ash.
