Rising tall over the lush rainforest of northern Costa Rica, Arenal Volcano is one of the country’s most iconic landmarks.
For years, it has captured the attention of travelers, not only for its dramatic cone shape, hiking trails, or stunning landscapes, but also for the fascinating mix of facts and myths tied to its history. Some stories come from science, others from local legends passed down through generations, and together they make Arenal feel even more special.
In this article, we’ll give you accurate details about this unique volcano while also sharing the surprising myths that make it a place full of wonder. Whether you’re planning a visit or just love learning about new places, Arenal has a story you’ll enjoy uncovering.
What Are Some Interesting Facts About the Arenal Volcano?
Besides its stunning shape and beauty, Arenal is full of details that make it stand out from other volcanoes in Costa Rica, which fascinates scientists, travelers, and nature lovers alike.
Let’s take a look at the most remarkable ones:
1. It’s One of the Youngest Volcanoes in Costa Rica
Arenal is considered a “young” volcano by geological standards—it was formed less than 7,500 years ago. That might sound ancient, but compared to older volcanoes in the region, Arenal is very young. Its youth explains why it has been one of the most active volcanoes in Costa Rica during the 20th century, with volcanic eruptions that shaped both the land and local communities.
2. Its Perfect Cone Shape Is Almost Too Perfect
One of the reasons Arenal is so iconic is its shape. Standing 1,633 meters (about 5,350 feet) tall, it has a nearly perfect cone silhouette. This symmetry isn’t common—most volcanoes have rugged, uneven forms from thousands of years of eruptions.
The almost perfect shape of Volcán Arenal makes it not only a geological wonder but also one of the most photographed and sought-after landmarks in our country.
3. It Lives Inside a Protected National Park
Arenal is at the heart of Arenal Volcano National Park, a protected area of more than 29,000 acres. The park safeguards rainforest, rivers, and wildlife, making it a hotspot for eco-tourism. Because it’s part of a national park, you can enjoy rainforest hikes, viewpoints, and educational tours that also support the conservation of the area.
4. It had a Massive Eruption in 1968
On July 29, 1968, Arenal erupted with incredible force after being dormant for over 400 years. The explosion devastated the nearby town, changed the local landscape, and marked the beginning of decades of frequent volcanic activity. However, out of this tragedy, the town of La Fortuna slowly transformed into the popular spot for tourism it is today.
5. It’s Resting, but Still Alive
The last time the volcano erupted was in 2010, entering a resting phase. Still, it’s far from being considered extinct. Scientists still classify it as an active volcano, keeping a close eye on its geothermal activity and underground movements. For visitors, this “resting but alive” state makes visiting Arenal fascinating—you can admire its quiet beauty while knowing the forces beneath the surface are very much present.
6. It Has Made the Region Burst With Life
Though eruptions can be destructive, they also leave behind incredibly fertile soil. The ash and minerals from Arenal’s past activity enriched the land, allowing the rainforest around it to thrive. Today, the area is bursting with life, including many animals like sloths, monkeys, and hundreds of bird species.
The volcanic activity also gave place to the natural hot springs that make Arenal so famous, creating relaxing spots where visitors can relax while surrounded by lush greenery.
7. It’s Surrounded by Remarkable Wildlife
The forests that surround Arenal Volcano are alive with some of Costa Rica’s most iconic wildlife. Most tourists who visit the area can spot colorful toucans soaring through the canopy, sloths napping high in the trees, and listen to howler monkeys calling out across the jungle.
Also, it’s possible to see tiny poison dart frogs, dazzling butterflies, and vibrant orchids. If you’re a nature lover, Arenal provides the chance to see something new and unforgettable.
5 Common Myths About Arenal Volcano Debunked
Arenal’s history has led to plenty of stories—some true, others not so much. Let’s clear things up with a few of the most common myths visitors hear about this famous volcano.
Myth #1: “Arenal erupts every night.”
Fact: Arenal was indeed one of the most active volcanoes in Costa Rica throughout the late 20th century, but it hasn’t erupted since 2010. These days, it’s in a resting state—no nightly fireworks here. You can still admire its impressive shape, but don’t expect glowing lava at sunset. (Smithsonian Global Volcanism Program)
Myth #2: “It’s too dangerous to visit.”
Fact: Visiting Arenal is perfectly safe. The volcano is closely monitored by scientists, and the surrounding area has been developed for eco-tourism with well-maintained trails and designated viewpoints. Tourists can safely explore the region without being at risk from volcanic activity.
According to the TripAdvisor Travelers’ Choice Awards, Arenal Volcano was selected as the sixth-best national park in the world (Instituto Costarricense de Turismo).
Myth #3: “You can hike to the crater.”
Fact: For safety reasons, hiking to Arenal’s crater is not allowed. Trails stop at safe distances, and visitors can only access designated paths in the national park or nearby reserves. The good news? You’ll still get spectacular views of the volcano without needing to go near the crater.
Myth #4: “You can still see lava flowing.”
Fact: While it’s true that Arenal erupted frequently in the past, lava flows have decreased significantly since the last eruption in 2010. What you can see today are old lava fields, which you can hike across in Arenal Volcano National Park.
Myth #5: “It’s Costa Rica’s only volcano.”
Fact: Costa Rica is actually home to more than 60 volcanoes, with at least five classified as active, including Arenal, Poás, Irazú, Rincón de la Vieja, and Turrialba. Arenal just happens to be one of the most popular ones because of its near-perfect cone shape and its history of activity.
Legends and Cultural Stories About Arenal
In Costa Rica, volcanoes aren’t just natural wonders; they’re also part of local stories and traditions. For generations, indigenous groups and nearby communities have shared legends to explain the mystery and power of these landscapes.
Here are two of the most well-known tales linked to Arenal:
The Love Story of Tenorí and Curubandé
The legend of Tenorí and Curubandé is one of Costa Rica’s most powerful tales of love and loss, tied to the volcanic landscapes of the Guanacaste region. It tells the story of two young lovers from rival indigenous clans in pre-Columbian times.
Curubandé, the daughter of a respected chieftain, was known for her deep connection to nature and her gift for understanding the elements. Tenorí, the son of an enemy chieftain, was brave and strong. Despite their families’ rivalry, the two fell in love in secret.
When their relationship was discovered, war broke out between their clans. Tenorí was killed in the fighting, leaving Curubandé heartbroken and alone. Pregnant and desperate, she fled to the mountains, where she gave birth in secret. To protect her baby from both clans, she made the tragic choice to throw the child into the volcano’s crater.
Grief consumed her, and she remained in the mountains as a hermit and healer. Over time, she became known as “the old woman from the corner,” or la vieja del rincón. According to the legend, the bubbling crater of Rincón de la Vieja Volcano is a reflection of Curubandé’s eternal sorrow—her tears for the love and child she lost.
The Dwelling Place of the God of Fire
To many of the Guatuso (or Maleku) people who lived around Arenal, the volcano was more than a mountain—it was sacred ground. One traditional belief is that Arenal is home to a God of Fire, a spirit who dwells within its belly. This deity embodies the heat, smoke, and volcanic forces beneath the earth.
Even though the volcano is now quiet, the legend holds that the god still watches, and that the hot springs, steam vents, and occasional tremors are signs of his presence.
