The Ultimate Guide to La Fortuna: Volcanoes, Thermal Springs, and Sloth Spotting
The Ultimate Guide to La Fortuna, Costa Rica: Volcanoes, Thermal Springs, and Sloth Spotting
Located beneath the shadow of Central America’s most iconic peak, La Fortuna is the premier eco-adventure hub of Costa Rica. From hiking over historic lava flows to soaking in river-fed mineral waters and spotting wildlife high in the canopy, finding the best things to do in La Fortuna, Costa Rica starts with understanding its three core attractions: Arenal Volcano, geothermal hot springs, and native sloth habitats.
1. Hiking Arenal Volcano: Trails, Views, and History
Arenal Volcano stands at 1,670 meters (5,479 ft) above sea level, defining the landscape of the Northern Lowlands. While the volcano has been in a resting phase since 2010, the surrounding reserves offer exceptional vantage points and volcanic terrain.
Top Arenal Volcano Hiking Trails
-
Arenal Volcano National Park (Sector Volcán): Follow the Sendero Coladas de Lava to reach the massive black basalt fields left by the 1992 eruption. The panoramic viewpoint provides direct lines of sight toward both the crater rim and Lake Arenal.
-
Arenal 1968 Private Reserve: Named after the historic 1968 eruption, this reserve features two distinct hiking loops across rugged lava beds and primary rainforest with panoramic volcano viewpoints.
-
Mistico Arenal Hanging Bridges: A 3.2-kilometer circuit featuring 16 suspension bridges that look out directly onto the volcanic peak through dense primary jungle canopy.
Local Travel Tip: Cloud cover often shrouds Arenal’s peak by midday. Schedule your hikes between 7:00 AM and 9:30 AM for the clearest views and best trail conditions.
2. Best Hot Springs in La Fortuna: Geothermal Relaxation
The magma chamber deep below Arenal heats natural underground waterways, feeding mineral-rich thermal rivers throughout the valley. Water temperatures typically range from 30°C to 42°C (86°F to 108°F).

3. Best Places to See Sloths in La Fortuna
Costa Rica is home to two sloth species: the nocturnal two-toed sloth (Choloepus hoffmanni) and the diurnal three-toed sloth (Bradypus variegatus). Because secondary rainforests and Cecropia trees are abundant around La Fortuna, it is one of the highest-density sloth habitats in Central America.
Where to Find Sloths in the Wild
-
Bogarin Trail (Sendero Bogarin): Situated right at the entrance of downtown La Fortuna, this flat, accessible 2.5-kilometer trail hosts a resident population of more than 25 sloths, as well as toucans and poison dart frogs.
-
Sloth’s Territory: A family-run conservation reserve dedicated to protecting natural sloth corridors and native Cecropia and Guarumo trees.
-
Danaus Eco-Center (Reserva Ecológica Danaus): A biodiversity reserve featuring day and night guided wildlife walks, a butterfly sanctuary, and natural lagoons home to caimans and water birds.
Wildlife Tip: Sloths blend naturally into the high canopy. Booking a local naturalist guide with a professional spotting scope significantly increases your chances of spotting them.
