One of the most popular tours starting from Antigua is the Pacaya Volcano hike.
The volcano is still active and during the trek you may happen to walk through rivers of glowing lava. Pacaya Volcano is an active complex volcano in Guatemala, which first erupted about 23,000 years ago and has erupted at least 23 times since the Spanish conquest of Guatemala. It rises to an elevation of 2,552 metres (8,870 ft).
