Volcán Irazu (3432 meters) is the highest volcano in Costa Rica. Because of this fact, many confused tourist believe this to mean that Irazu the highest peak in Costa Rica. In reality there are several higher peaks in the Cordillera de Talamanca. There have been recorded eruptions of Irazu since 1723. The last major eruption occurred on March 19, 1963, the day John F. Kennedy arrived on a visit. Ash from this eruption covered the whole Central Valley, including the capital San Jose, and piled up to 0.75 meters (2 feet) deep! There have been no major eruptions since 1963, but the crater is still boiling and steaming. There was a small eruption in 1994. The ash from the volcano makes the surrounding hillsides and valleys very fertile.
There are two major craters of Volcán Irazu. The Principal Crater is 1050 meters wide and 300 meters deep. Diego de la Haya Crater is 690 meters wide and 100 meters deep and contains a lake.
From the summit, it is possible to see both the Caribbean and Pacific, but such clear days only happen on 3-4 days a year. There is a paved road to near the summit of Irazu, but there are several short trails around the crater area.

Since there is a road to the summit, there isn’t too much hiking here, at least not in a mountaineering or long trekking sense, but there are some very good short hikes in the summit area. There is a 1 km (0.6 mile) long trail from the summit parking lot that goes to a look out of some of the craters and this hike is highly recommended. There is also a longer trail, marked by a pedestrian sign that gets even closer to the craters as well.
For longer hikes, check out the nearby Volcán Turrialba.
