If you can get past these things however, hiking Acatenango to see Volcan Fuego erupt beneath the stars might just be one of your favorite travel memories. Toast Marshmallows on Volcano PacayaIf an overnight trek sounds like a bit too much, you can still experience one of Guatemala’s active volcanoes. Once at the top, you can experience the moon-like landscape and even toast marshmallows over hot rocks. But don’t expect red, flowing lava here – you’ll have to venture to Volcan Fuego to see that. *2021 Update: Because of its recent hyperactivity, Volcan Pacaya is closed for hiking until further notice.
