Arenal, Costa Rica
Accommodations around Arenal are plentiful, very scenic, beautifully manicured, and range from the more economical all the way to very pricey, all-inclusive luxury hotels. Arenal is considered a prime spot for a vacation home. Because of the volcano’s near constant activity, hot springs are plentiful at resorts all around Arenal. Spas that offer gourmet cuisine, yoga, massage, and hot pools of differing types with varying mineral concentrations are very successful in the area.
Just to the west of Arenal lies Lake Arenal, a natural lake that was enlarged to create Costa Rica’s largest hydro-electric power project. Lake Arenal is picturesque, perfect for windsurfing and fishing, both of which are popular activities at the lake.
At roughly 7:30 a.m. on Monday July 29, 1968 – after having lain relatively dormant for over 400 years – Arenal Volcano erupted with violence and fury. Extreme eruptions and volcanic activity continued for several days, killing some 87 people and burying over 15 square kilometers in rock, lava and ash. The eruptions affected a total of over 232 square kilometers in the surrounding area to varying degrees, with damage to crops, property, livestock and forests.
At the height of its activity this La Fortuna volcano was spewing out massive amounts of lava and ash and tossing giant rocks for distances of up to a mile at speeds of some 600 meters per second.
The explosions formed three new active craters.
Since that time, Arenal Volcano has maintained nearly constant activity ranging from soundless explosions with large mushroom-shaped clouds of ash overhead to booming explosions sending hot rocks nearly a kilometer into the air to pyroclastic explosions highlighted by rushing gases and flowing lava pouring down the side of the volcano. For visitors to Costa Rica, volcano viewing is the most promising at Arenal – no other volcano has been this consistently active.
Arenal Volcano rises to approximately 1633 meters at its summit, although the exact summit height changes frequently due to the volcanic activity.
Prior to the 1968 eruption, Arenal Volcano was a nearly perfect cone-shaped, rainforest blanketed volcanic mountain with minor fumarole activity. Local residents had named it variously: Arenal Peak, Pan de Azúcar (Sugarloaf), Canasta Volcano, and Río Frío Volcano.
The area around Arenal Volcano has been home to indigenous populations for thousands of years. Over this time, these residents have weathered scores of periods of intense volcanic activity.
In Costa Rica, volcanoes are a natural part of the landscape, contributing to the area’s history and folklore, The Guatuso Indians, for example, believed the volcano was home to the God of Fire.
In geological terms, the Arenal Volcano is relatively young, only some 4000 years old. Prior to the 1968 eruption, the volcano’s last major eruption has been dated at around 1500 AD and lava flows from this period have been tentatively identified.
The Arenal volcano produces energy for Costa Rica – Next to the eruptive natural wonder at the Arenal Volcano Natural Park is a human-enlarged lake that supplies more than 40% of Costa Rica’s hydroelectric supply. Its taps the natural winds and volcanic activity to produce this power.
There are four campsites that are close to the Arenal volcano. Since there are over 40 Arenal volcano hotels in various price ranges with multiple commodities, any visitor can stay as close as possible to the erupting volcano.
Usually, large eruptions occur every 3 to 4 years. But daily eruptions occur every few minutes. However, this time can vary, so be patient! During these eruptions, lava flows from either side of the mountain, cascading down and surrounding the area of the park.
Visit Arenal volcano through many Costa Rica all inclusive resorts – Many of the hotels in the Tamarindo and Limon area supply all-inclusive packages that include a visit and a tour of the Arenal volcanoes. Check with your hotel to book a package.
