Acatenango is a stratovolcano in Guatemala, known for its challenging but rewarding overnight hike offering spectacular views of the nearby active volcano, Fuego. The ascent is strenuous, generally taking 4-6 hours, with an overnight stay near the summit for optimal viewing of Fuego's eruptions, followed by a descent of 2-4 hours. Due to the steep and rugged terrain, it's not considered accessible for individuals with mobility issues. A guided tour is highly recommended, especially for safety and logistical support, although experienced hikers may attempt it solo. The dry season (November to April) is generally preferred for better visibility and safer hiking conditions; the rainy season can make the trails slippery and obscure the views. The cost, including transportation, guide services, park entrance fees, and basic camping equipment, typically ranges from $75 to $150 USD per person. Expect the overall visit duration to be around 24-36 hours.
