La Fortuna Costa Rica: Adventures at the Foot of Arenal Volcano

Arenal Volcano (Volcán Arenal) dominates the landscape around La Fortuna with its near-perfect conical silhouette rising to 1,670 meters. For most of the second half of the 20th century, Arenal was considered one of the most active volcanoes in the Americas, regularly producing lava flows, pyroclastic events, and ash eruptions that made for spectacular nighttime viewing from La Fortuna and the surrounding area. The most catastrophic eruption in recent memory occurred on July 29, 1968, when Arenal suddenly reawakened after 400 years of dormancy, destroying the nearby town of Tabacón and killing 87 people.

After decades of near-constant activity, Arenal entered a relatively quiet phase around 2010 that continues to the present. Visible lava flows and spectacular eruptions are no longer regular features, though the volcano is still geologically active, with fumarolic activity, occasional small phreatic events, and persistent geothermal activity throughout the region. Volcanologists consider Arenal still active and capable of renewed activity. The volcano's perfect cone shape remains as dramatic as ever and continues to be one of the most photographed mountains in Central America — when clouds permit its summit to be visible.

Arenal Volcano National Park (Parque Nacional Volcán Arenal) was created in 1991 to protect the volcano and the surrounding rainforest. Two main trails access the park: the Las Coladas trail passing over old lava fields from the 1968 eruption, and the Los Tucanes trail through secondary forest with good wildlife spotting opportunities. Views of the volcano from within the park are excellent on clear days, though the summit is frequently obscured by cloud cover. The park entrance is located about 14 kilometers from La Fortuna town, and the park station near the entrance has exhibits on the volcano's geology and history.

The geothermal heat of Arenal Volcano heats underground water throughout the La Fortuna region, producing natural hot springs that are one of the area's most beloved attractions. The experience of soaking in naturally heated mineral-rich water surrounded by rainforest, with Arenal Volcano looming in the background, is genuinely extraordinary and has made La Fortuna synonymous with hot spring tourism in Costa Rica.

The hot spring options range from luxury resort experiences to natural free pools. Tabacón Grand Spa Thermal Resort, built near the site of the town destroyed in the 1968 eruption (the name refers to the tobacco plants grown there by early settlers, not to the disaster), is the most famous and elaborate, featuring extensive pools at varying temperatures, waterfalls, a full-service spa, and a restaurant set in a beautifully landscaped tropical garden. The Baldi Hot Springs resort offers similar amenities at a slightly lower price point with a more water-park-like atmosphere. The Eco Termales resort is smaller and more intimate, limiting visitor numbers for a quieter experience.

At the budget end, the free natural hot springs on the Río Cholín at the base of the Tabacón property (accessible from a pullout on the main road) provide a genuinely natural soaking experience without any facilities. These pools were created by the hot volcanic water mixing with the cool river and are a beloved local secret known to budget travelers. Several hotels near the La Fortuna area also have their own hot spring pools fed by geothermal water, offering their guests private soaking access without the crowds of the major resort facilities.

The Catarata La Fortuna (La Fortuna Waterfall), located about 5 kilometers south of La Fortuna town, is one of the most stunning waterfalls in Costa Rica. The waterfall drops approximately 75 meters into a circular pool surrounded by lush green walls of fern-covered volcanic rock, creating a cool, misty amphitheater that is dramatically beautiful and genuinely refreshing to swim in. The pool at the base is safe for swimming and the cold volcanic water is a wonderful contrast to the heat of the region.

Access to the waterfall is via a private property and trail. Visitors pay an entrance fee (approximately $18 USD as of 2025) to access the trail, which descends steeply (approximately 500 steps) to the base of the waterfall. The descent takes about 20 minutes; the ascent on the return is more strenuous and takes 30–40 minutes. Several viewpoints along the descent offer excellent photography perspectives before reaching the base. Arriving in the morning provides the best lighting for photography — the canyon orientation means afternoon light is less flattering and afternoon heat makes the ascent more demanding.

The area around La Fortuna Waterfall is also excellent for wildlife observation. Toucans, motmots, and other forest birds are regularly seen along the trail. The vegetation around the waterfall is primary rainforest, and the mist zone at the base supports spectacular fern and bromeliad communities. Several tour operators offer guided hikes to the waterfall that combine the visit with a horseback ride through the surrounding countryside. Swimming in the pool requires a life jacket in the deeper sections and should be approached cautiously if unfamiliar with the current patterns.

La Fortuna has one of the most comprehensive adventure activity menus in Central America, with dozens of operators offering everything from mild to extreme experiences. White-water rafting is available on two rivers: the Río Toro offers Class III–IV rapids in a beautiful canyon setting, while the Río Sarapiquí (accessed through the northern rainforest) provides a longer, wilder experience. Full-day rafting trips include transportation, professional guides, safety equipment, and lunch. The Río Pacuare, considered one of the world's best white-water rivers, is accessible as a longer day trip.

Zip-lining canopy tours are enormously popular, with several operators including Arenal Mundo Aventura, Sky Adventures Arenal, and Ecoglide offering lengthy zipline circuits through the forest with volcano views. The Sky Tram gondola ride at Sky Adventures provides a more sedate way to access the forest canopy with excellent volcano views and birdwatching opportunities before taking the zip lines back down. Hanging bridges walking tours through the forest canopy are offered at several reserves near La Fortuna, providing a stable platform for birding and wildlife spotting at canopy height.

Caving in the Venado Caverns (Cavernas de Venado), a network of marble limestone caves approximately 30 kilometers from La Fortuna, provides a unique underground experience with stalactites, stalagmites, bats, and underground rivers. Guided cave tours wade through waist-deep water in some sections and require headlamps. Night jungle walks organized by local naturalist guides provide access to nocturnal wildlife including poison dart frogs, sleeping birds, kinkajous, and insects not seen during daylight hours. Kayaking and stand-up paddleboarding on Lake Arenal are popular lower-intensity options.

The rainforest surrounding La Fortuna and Lake Arenal is extraordinarily biodiverse, hosting representatives of most of Costa Rica's iconic wildlife. The Caño Negro Wildlife Refuge, about 85 kilometers north of La Fortuna via Ciudad Quesada, is one of the best bird watching destinations in Central America. Boat tours through the Caño Negro wetlands encounter jabiru storks (the largest flying bird in the Americas), roseate spoonbills, anhingas, caimans (spectacled caiman), river turtles, and an extraordinary concentration of neotropical water birds.

Within the La Fortuna area, sloths are commonly spotted in the cecropia trees along roads and forest edges, particularly near the town itself. Both two-toed sloths (Choloepus hoffmanni) and three-toed sloths (Bradypus variegatus) occur in the area. Howler monkeys, white-faced capuchins, and spider monkeys inhabit the surrounding forest. The area around Lake Arenal's northern shore has excellent birding for toucans, trogons, and hummingbirds. A wildlife rescue center, Proyecto Asis, in nearby La Tigra, allows visitors to observe and interact with rescued sloths, coatis, and various other animals in a responsible context.

The Mistico Hanging Bridges Park provides excellent wildlife access through a network of suspension bridges and forest trails where skilled naturalist guides can identify birds, reptiles, and mammals. Several private reserves adjacent to Arenal Volcano National Park also offer guided natural history tours. Night tours organized through local guide services provide access to the fascinating nocturnal world of the tropical rainforest, with species including red-eyed tree frogs, tarantulas, kinkajous, porcupines, and various owl species regularly encountered.

La Fortuna town is the most developed tourist hub in inland Costa Rica, with accommodation spanning every budget category from backpacker hostels at $15 per night to luxury rainforest lodges and thermal-spa resorts at $500+ per night. The town center is compact and walkable, with the central square, park, and church (with its famous Arenal Volcano backdrop) surrounded by tour operator offices, restaurants, souvenir shops, and mid-range hotels.

For luxury experiences, the Nayara Springs resort is consistently rated among the best boutique hotels in the Americas, featuring private villa accommodations with individual hot spring plunge pools, exceptional service, and multiple restaurants in a beautifully landscaped rainforest setting with volcano views. The Arenal Observatory Lodge occupies a former Smithsonian Institution research station on the lower slopes of Arenal Volcano itself and offers the closest accommodation to the volcano with outstanding views and nature access. The Tabacón Thermal Resort combines the most famous hot spring facility in the country with elegant bungalow accommodation in a spa-resort format.

La Fortuna town's restaurant scene has grown considerably, with dozens of options ranging from traditional Costa Rican sodas serving gallo pinto and casados to international restaurants offering Italian, Mexican, Asian fusion, and sophisticated Costa Rican cuisine. Don Rufino is the town's most celebrated restaurant, known for quality Costa Rican beef and excellent service. The Kappa Sushi has a devoted following for Japanese food in an unlikely location. For budget eating, the soda strip along the main street offers excellent traditional food at very low prices. Most restaurants are clustered around the central square and on the main road (Avenida 318) within easy walking distance.
