Parque Nacional Volcán Poás

Just 37km north of Alajuela by a winding and scenic road is Parque Nacional Volcán Poás, the home of a 2704m active volcano. Violent eruptions hadn't taken place for more than 60 years when rumblings began in 2014; there were further significant eruptions in April and June 2017, and the park did not open again until August 2018.
