At 5,400 feet, Arenal Volcano is the most iconic volcano in Costa Rica. Considered a relatively young volcano, it is estimated to be about 7,000 to 7,500 years old and was formed by the now extinct Chato Volcano. Arenal is an andesitic stratovolcano and boasts a picture-perfect cone shape which can be seen from most of the hotels and attractions in the surrounding area. It features one crater which spans about 460 feet.
On July 29, 1968 Arenal unexpectedly erupted after being dormant for hundreds of years. This massive eruption caused significant damage, wiping out the town of Tabacon and leaving 5 square miles covered in lava, rocks and ash. After this eruption, the volcano stayed mildly active until July 2010, and visitors to the area could witness small eruptions and lava flow. Since 2010, however, the volcano has been dormant, and no lava flow or eruptions can be seen currently. Smoke from the top of the crater can still be seen from time to time.
Although it has not been active for a few years now, it is not possible to get up close and personal with the volcano. There are, however, wonderful guided trail hikes through Arenal Volcano National Park that follow around the base of the volcano where visitors can explore the dried lava fields and amazing flora and fauna in the area. These hikes are great for wildlife viewing, birding, and photo opportunities.
One of the most popular reasons to visit Arenal Volcano (besides all of the adventure activities in the area) are the wonderful volcano heated hot springs that come from the geothermal activity beneath Arenal. There are many hotels that feature their own private hot springs, and other off-site hot springs that can be visited with a full-day or half-day pass.
Best Time to Visit
Since there is no distinct weather pattern in Arenal, it is great to visit this region any time of year. There is always a chance of rain in this area, but that’s what keeps it green and lush year-round. It can get a bit cooler here in the evening, so a light jacket or windbreaker is a good idea.
