I'm from Mexico, about 2 hours away from Guatemala City—close enough to watch an eruption of the Fuego volcano.
So, we made the decision to go to Antigua, Guatemala for 4 days:
• Day 1: Arriving in Guatemala; transport to Antigua (takes about 1 hour).
• Day 2: Ascent to Acatenango and Fuego volcanoes.
• Day 3: Descent and return to Antigua.
• Day 4: Transport to the airport and back to Mexico.
Yes, the volcano erupts every 10 to 15 minutes.
