This begs the question: why? How could this sleepy hamlet attract such a sheer quantity of tourists? The answer lays slightly West.

Protruding from the foothills below, Volcan Arenal, or Arenal Volcano, is a stratovolcano that rises tall and proud. At a whopping 1700 meters, Arenal volcano is one of the largest volcanoes in all of Costa Rica. Many people flock to Arenal to marvel at the beauty of this geological spectacle.

With its perfectly conical slopes, and bountiful lowland rainforests all around, the region of Arenal and La Fortuna is one of Costa Rica’s top tourist destinations.

A Guide to Visiting Arenal in Costa Rica

History of Arenal, Costa Rica

Arenal is the youngest and, up until 2010, the most active of all 67 volcanoes found in Costa Rica.

The infamous eruption of 1968 ended a dormancy period of 400 years and claimed the lives of 87 people. Without warning, the volcano violently erupted over a period of a few days. Towns were buried in a thick layer of ash, large numbers of livestock were killed and crops were destroyed.

The eruption spewed rocks for miles around, some weighing many tons. To this day, the devastation from this eruption can still be seen from the scaring on the Western slopes.

It is a popular myth from the region that the neighboring town El Borio was renamed La Fortuna, after the eruption. Meaning “the fortunate”, it is thought that this town was one of the few that escaped destruction. Yet this myth is widely disputed.

Since 1968, the mighty volcano erupted almost daily and displayed mild explosive activity from the summit crater. This, coupled with lava flows, has attracted tourists from around the world. Arenal was officially declared dormant once more in December 2010. Today, although it is highly unlikely to see any explosive activity, a buzz of excitement can be felt from all around the region.

Heading West once more, you will find Lake Arenal. In 1979, the naturally occurring lake was expanded to nearly three times its former size. The town of Arenal was flooded to allow for the expansion, and can now be found on the Northern shores as Nuevo Arenal.

Now, it is the largest freshwater body in Costa Rica and a variety of recreational activities, from fishing to boating, can be found here. However, the main function of the lake serves as a dam and hydroelectrical plant which is thought to power 12% of Costa Rica’s electricity demands.

What to do in Arenal, Costa Rica

Arenal Volcano National Park

Due to the volcanic uncertainty of the region’s nature, climbing the slopes of Arenal is strictly forbidden. Having said this, one of the key attractions to Arenal and the surrounding areas is the spectacular hiking on offer.

Many tourists flock to the Arenal Volcano National Park to observe the incredible views of the dominating volcano and the high biodiversity of the lowland rainforest ecosystem. Some trails, such as Sendero Colada and Tucanes pass through some stunning scenery, including the solidified lava views.

To optimize your visit to the National Park, it is worth considering booking a guided tour with a specialist naturalist. Many of the guides have spent their entire lives around Arenal and La Fortuna, thus have a rich understanding of local flora and fauna – and where to find them.

Some of the most frequently observed wildlife sightings within the National Park are white-faced capuchin monkeys, coatis, parrots, and sloths.

One of the best ways to appreciate the jungle is to book a night tour. This is a great way to discover how life has adapted to the twilight hours; a time when most of us are tucked away in bed. The Twilight wildlife safari offers fantastic and unique tours via Rio Peñas, a nearby river, where you will have the opportunity to observe nocturnal animals in their natural habitat.

Hot Springs

Hot Springs - what to do in Arenal Costa Rica

After a day of strenuous activity – perhaps from hiking within the National Park or cycling around Lake Arenal – muscles can soon become achy. If only there was a nice, hot bath you could soak in. Fortunately, you’re in luck!

Underground thermal vents heat the water, which bubbles to the surface to form the world-famous Arenal Hot Springs. The high abundance of volcanic minerals found within these rivers and pools are therapeutic, having been used by indigenous tribes for millennia.

With a variety of hot springs to choose from, and depending on your budget, there is something for everyone. Such examples of local hot springs include Tabacon, Baldi, and The Springs, however, there are more in the area, waiting to be discovered.

Soak in the warm waters and listen to the jungle melodies reverberate around you. Feel the refreshingly cool rain on your skin and the steam rising up. The tropical ambiance here is otherworldly. Many of the privately-owned hot springs stay open late into the night, so guests can enjoy this relaxing experience at their own leisure.

La Fortuna Waterfall

The way is paved with over 500 steps. Unlike some of the other excursions around Arenal, the hike only lasts 15 minutes, each way. Not only are you rewarded with spectacular views, but a refreshing swim in the cool pools formed at the base of the falls. Perfect on a hot day.

La Fortuna: Horseback Riding at Mistico Park, Arenal Volcano


One of the more distinctive ways to witness the sprawling mass of verdant green rainforest is to hit the skies. Offering incredible views extending for miles in all directions (if the weather allows), ziplining rewards you with encounters with local wildlife; including spectacularly colored birds and insects, in a thrilling, wild-hair adventure.

Ziplining is an exhilarating experience for all to enjoy. As you whiz down the suspended cables, you will feel a thrilling adrenaline rush you would be pushed to find doing any other activity. On a clear day, the views are unprecedented, however, there is a mysterious and magical excitement to be had if you happen to shoot down the ziplines in cloudy and murky conditions – you just don’t know what to expect in the gloom of the jungle.

Sloth Tour

Arenal is one of the only places in the country where you will be able to spot both species of sloth. Due to the perfect climatic conditions, both species (two-toed and three-toed sloths) thrive in the jungle ecosystems here and live harmoniously together.

Many companies offer wildlife tours that seek to spot elusive, often nocturnal creatures. With knowledgeable guides, who know exactly where to look, spotting these camouflaged, balls of fur in the canopy have never been easier.

White Water Rafting

This is another one for the adventurers at heart. There are three main rivers found near Arenal and the surrounding areas: Toro, Balsa, and Peñas Blancas – with each catering to a different level of rafting expertise. Out of the three, Peñas Blancas is probably the slowest flowing, offering leisurely trips floating down the river and the best chance of spotting wildlife.

For the thrill-seekers and avid rafters, a trip towards the highlands of Poas may yield the best results, with exciting and fast-paced rapids, and large sweeping waves. For the best of both worlds, the best option would be to explore the Balsa River. Along this stretch, you will encounter both calm and rapid sections of the river.
