Arenal Volcano

Located in Parque Nacional Volcán Arenal,14km west of La Fortuna, Arenal Volcano is one of Costa Rica’s top natural attractions. Though still technically active, it’s been quiet since 2010, with no lava or explosions and only the occasional release of gas. It’s a spectacular sight and was given protected status in 1995. In addition, the park has several good walking trails, and the surrounding area is a hotbed of hot springs and adventure activities. Plan your trip to Arenal Volcano with our local experts.

The best travel tips for visiting Arenal Volcano

Arenal Volcano (Volcán Arenal) is Costa Rica’s youngest stratovolcano – that’s the technical term for a steep, conical volcano created by the eruption of thick lava flows. It is one of the best national parks in Costa Rica.

Arenal’s growth over the ages has been characterized by massive eruptions every few centuries. At the time of its most recent eruption in the late 1960s, Arenal seemed to be nothing but an unthreatening mountain. Indeed, locals had built small farms up its forested sides. 

Then, on July 29, 1968, an earthquake shook the area, blasting off the top and to form the majestic, lethal volcano seen today. The volcano killed 78 people that day, and has been active ever since, though it’s currently in a quiet period. 

While history would suggest it’s not due another major blowout for a few hundred years, and despite the recent years of slumber, Arenal is still very much an active volcano. In fact, technically everything between the volcano and the roads that run from La Fortuna to Laguna de Arenal and El Castillo lie in a high-risk area. 

As a result, some safety tips are worth bearing in mind — never veer from trails or guided tours, and don’t attempt to hike anywhere near the crater. Lethal gases, ballistic boulders and molten rock can appear or change direction without warning.  

Being one of Costa Rica’s top natural attractions, Arenal Volcano is certainly worth visiting during your trip. 

Best things to see and do near Arenal Volcano

This volcano, and it's surroundings, is one of the major attractions in Costa Rica. And it's not difficult to understand why when you visit the place. The natural beauty is unparalleled and there are so many things to do that you could easily spend a week here.

Make sure to put these activities on your list.

#1 Hike trails in Arenal Volcano National Park

Arenal Volcano National Park boasts a few good trails, all accessed from the main park entrance. These include the Lookout Point Trail (1.3km) and the Las Coladas Trail (2.8km), which heads southeast to a lava flow from 1992.

The Los Tucanes Trail (4km), also accessed off the road up to the Arenal Observatory Lodge, takes you to the part of the forest that was flattened by the 1968 eruption.

You may see some wildlife on these hikes — birds (including oropendolas and tanagers) and agoutis are particularly common. 

Although the park has a simple café, it’s best to take a picnic lunch and plenty of water if you intend to walk extensively.

#2 Take one of many great tours

Arenal is known for its majestic Arenal Volcano and the surrounding lush rainforests, making it a popular destination for tourists looking to immerse themselves in nature. There are plenty of tours available to explore the area, but some of the best include the Arenal Hanging Bridges tour, which takes visitors through a series of suspended bridges offering stunning views of the surrounding canopy and wildlife.

Another popular option is the Arenal Volcano National Park tour, which includes a hike to the volcano's base and a visit to the park's hot springs. For those looking for a bit more adventure, there are also zip lining and white water rafting tours available.

#3 Explore Reserva Mirador El Silencio

A number of hikes on the fringes of Arenal Volcano National Park are worth exploring, including those at the Reserva Mirador El Silencio. You’ll find this 5km north of the park entrance. 

The four trails at this reserve lead through primary forest sheltering peccaries and spider monkeys to a lookout at the foot of the volcano.

It's also a great place for bird-watching — expect to see plenty of parrots, toucans, tanagers, honeycreepers and oropendolas.

#4 Fish, kayak, cruise and windsurf on Laguna de Arenal

The Laguna de Arenal makes what would otherwise have been a pretty area into a very beautiful one.

Pretty as it is, it’s actually a man-made body of water created when the far smaller original lake was dammed in 1973. The resulting Arenal Dam now generates much of the country’s hydroelectricity. 

The lake is an excellent fishing spot. The rainbow bass — an iridescent fish found only in freshwater lakes and rivers in Costa Rica, Nicaragua and Honduras — is particularly prolific.

Laguna de Arenal is also the country’s prime spot for windsurfing. This is done mainly out of Tilarán, on the western side of the lake.

#5 Visit La Fortuna waterfall

4km southwest of La Fortuna, the dramatically sited La Catarata de La Fortuna is the epitome of a picture-book cascade. It's clear to see why it's one of the best waterfalls in Costa Rica. 

A tall, thin stream plunges prettily from a narrow aperture in the rocky heights 75m above, forming a foaming pool among rocks and rainforest below. 

From the ticket booth, a path leads 600m vertically down to the base of the falls, where a series of pools provide a tempting spot for a dip. Though swimming is not recommended due to flash floods, a lot of people do it anyway.  

There’s a mirador (signposted) 200m along the trail for those who'd rather look from a distance. This gives great views across the steep valley and its heavily forested floor to the thin finger of the cascade. 

Make sure you wear waterproof shoes, and be aware that the paths can be slippery.

#6 Soak in hot springs

Due to the volcanic activities, the area around Arenal Volcano is known for its natural hot springs. Here are some of the best. 

Balneario Tabacón

The glitziest of the main hot springs, and the destination for most tourists is Balneario Tabacón. Fed by a magma-boiled underground thermal river, the water temperature here ranges from 27°C (80°F) to about 42°C (108°F).

The complex comprises fifteen mineral-rich pools, most of which are secluded among rich vegetation. Several are set beneath waterfalls, so you can manoeuvre yourself under the cascades for a pummelling massage.

Baldi Hot Springs

Baldi Hot Springs is more accessible than Tabacón for those without transport. While it lacks the classy touches of its rival, it’s significantly cheaper and offers many of the same facilities.

It boasts 25 steaming pools, including Roman-style baths and waterfall-fed pools. Younger soakers will love the three waterslides.

Ecotermales Fortuna

Fronted by imposing wooden gates, the exclusive-looking Ecotermales Fortuna has five cascading thermal pools of varying temperatures set in idyllic forested surrounds.

It’s stylishly low-key, and only 100 people are allowed in during any of the allotted times, so be sure to book ahead in high season.

Termales Los Laureles

Termales Los Laureles is the least expensive official hot springs in the Arenal area, and popular with Ticos.

Four simple pools (one with slides) are set around a very ordinary garden, but the volcano views are sensational. Bring your own food and booze and make a night of it.

Best places to stay

Budget travellers visiting Arsenal volcano usually stay in or around La Fortuna, while people with their own transport and/or a bit of money tend to head to the lodges surrounding town. 

Though some of these are quite remote and local public transport is erratic or non-existent, many places offer a free shuttle service into town. 

The nearby communities of Chachagua, 10km southeast of La Fortuna, and El Castillo are more relaxed alternatives to the main town, but still close enough to the action.

Among the top places to stay near Arenal Volcano, we recommend Arenal Observatory Lodge. It’s just 1.8km from the crater, with extensive grounds and rustic rooms looking out at Arenal.
