Although you can't drive up to its summit as you can at Poás and Irazú, Volcán Turrialba is an impressive sight from a distance, albeit with some major precautions these days. The volcano has been increasingly active since early 2010 and a series of explosions in spring 2015 spewed out steam and ash to far reaches of the country. A heavy content of sulfur dioxide in fumes emanates from the volcano, a phenomenon that has taken its toll on plant and animal life here. If you suffer from a heart or respiratory condition or are pregnant, stay away. The immediate area, beyond the Volcán Turrialba Lodge (see Sports and the Outdoors), remains closed off to residents and visitors at this writing.
