Turrialba and Irazu are the two highest volcanoes in Costa Rica, and both have a similar construction in terms of their type of volcano and the ecology around them.
Turrialba is the most active volcano in Costa Rica, but for many years the most active volcano was Arenal. The types of eruptions between the two different volcanoes of Arenal and Turrialba make for unique experiences. Most of Turrialba’s eruptions are phreatic which means that steam is released and ash pours from the sky. These are not so fun, because the ash falling from the sky can be toxic for people living in the area. Arenal produced effusive lava eruptions with low amounts of gas like those find at volcanoes on the Hawiian Islands. This helped to popularize the area for tourists who would come to relax in thermal hot springs while watching the lava slowly ooze its way down the mountain.
Turrialba is still a striking image on the skyline, and one of the most exciting and beautiful river rafting trips can be found passing by in the Pacuare River. However, the recent eruptions at Turrialba have caused some problems for tourists who want to travel through the area, and Turrialba Volcano National Park has been closed to guests a few times both this year and last. If planning to visit the park, be sure to plan accordingly for any unforeseen issues that might develop as a result of natural events.
