Irazu Volcano National Park
Central Highlands Region of Costa Rica
Irazu Volcano, still active, last made international headlines when it erupted in 1963 on the day that former US President John F. Kennedy visited the country. The eruption decimated crops in the area but left the soil enriched for decades to come. The last noticeable activity came in 1996, and since then Irazu has been a quiet giant. Reaching upward of 11,260 ft (3,432 m), Irazu is the tallest volcano in Costa Rica.
