10 Things to Do in Arenal Costa Rica

You’ll find endless adventures around Arenal’s towering volcano, from hiking the 1968 Lava Flow Trail through hardened volcanic terrain to rappelling down 200-foot waterfalls during canyoning expeditions. Cool off at La Fortuna’s emerald swimming hole, then soak in geothermal hot springs heated to 106°F. Soar through rainforest canopies on ziplines reaching 70 km/h, spot three-toed sloths on wildlife tours, and navigate Class II-III rapids on the Balsa River. Discover how these experiences combine for an unforgettable Costa Rican adventure.

Hike the Arenal 1968 Lava Flow Trail Through Ancient Volcanic Destruction

When Arenal Volcano erupted in 1968, it transformed from a dormant giant into one of Costa Rica’s most active stratovolcanoes. It hurled lava and volcanic blocks at speeds reaching 1,200 mph across the surrounding landscape.

You’ll find the private reserve 25 minutes from La Fortuna on Route 142’s western flank. Choose between two marked loops: the easier Lava Flow Trail (2.5-3 km) or the moderate-to-difficult Forest Trail (4.5-4.7 km). The combined circuit covers 5.4-7 km with 210 meters elevation gain, taking 2-3.5 hours.

You’ll traverse hardened aa-type lava flows, impact craters, and scattered boulders while following the 1968 eruption’s destructive path. The eruption destroyed three towns and caused significant damage to the surrounding area. The grippy lava rock provides excellent traction despite uneven terrain.

Cool Off at La Fortuna Waterfall’s 200-Foot Jungle Cascade

After exploring the volcanic devastation from Arenal’s explosive past, you’ll want to cool off at La Fortuna Waterfall. Here, a spectacular 230-foot cascade plunges into an emerald pool surrounded by dense rainforest. Located just 3 miles from downtown La Fortuna, this iconic attraction sits within a 210-acre biological reserve.

You’ll descend approximately 530 steps on a well-maintained trail with handrails and rest platforms—plan 15 minutes down and 30 minutes back up.

Swimming’s permitted in designated areas when conditions allow, though you’ll need to navigate slippery boulders. During rainy season, expect stronger currents and restricted access.

Arrive early around 7:00 AM to avoid crowds of 1,000 daily visitors. Your entrance ticket also includes access to an Orchid Garden showcasing native Costa Rican species.

Entrance costs $18-20 for international adults, with proceeds supporting local conservation efforts.

Soak Your Hiking-Weary Muscles in Natural Hot Springs

Since Arenal Volcano’s geothermal activity heats underground water that emerges at temperatures between 90-106°F, you’ll find the perfect remedy for post-hike muscle soreness in the region’s renowned thermal springs.

The mineral-rich waters contain calcium, magnesium, and sulfates that promote muscle relaxation and improved circulation.

Tabacón offers Costa Rica’s largest network of naturally flowing thermal pools within a rainforest reserve, featuring cascading waterfalls and hot river experiences.

The Springs Resort provides multiple pools with direct volcano views, while EcoTermales Fortuna maintains eight tranquil pools focused on peaceful soaking.

Paradise Hot Springs delivers boutique-style relaxation with fewer crowds.

Most properties integrate hydromassage features and alternating hot-cool pools that reduce inflammation and ease tension in your legs, back, and shoulders after challenging hikes. For budget-conscious travelers, Rio Chollín Hot Springs offers a free option with natural pools in a beautiful setting.

Soar Through the Rainforest Canopy on World-Class Ziplines

Seven to twelve cables stretch across Arenal’s rainforest canopy, creating some of Costa Rica’s most exhilarating zipline experiences where you’ll soar at speeds up to 70 km/h through multiple forest layers.

Arenal Sky Adventures combines a 20-minute aerial tram ascent with a 7-cable circuit offering panoramic volcano and Lake Arenal views during your 2.5-hour adventure.

Big AMA’s 12-cable course spans 2 miles across 560 hectares of protected forest, featuring some of Arenal’s longest single spans plus views of La Fortuna and Pino Blanco waterfalls.

Professional operators use automatic braking systems and certified safety equipment including dual-attachment harnesses.

You’ll traverse deep ravines above the Arenal River valley while spotting monkeys and birds between adrenaline-pumping descents. Many parks offer hanging bridges and cultural visits to enhance your canopy adventure beyond just ziplining.

Walk Among the Treetops on Arenal’s Hanging Bridge Networks

Sixteen bridges spanning 600 acres of pristine rainforest reserve offer you an intimate ground-level alternative to Arenal’s high-speed ziplines, letting you walk slowly through multiple canopy layers while observing wildlife at your own pace.

You’ll traverse suspension spans up to 330 feet long at heights reaching 180 feet above the forest floor, providing unobstructed views of emergent tree crowns and occasional Arenal Volcano vistas.

The 2-mile trail system takes 2-2.5 hours to complete, featuring well-maintained paths suitable for most fitness levels.

You’re likely to spot sloths, howler monkeys, toucans, and over 350 bird species among 700+ plant varieties.

Steel-constructed bridges include safety railings and anti-slip surfaces, with guided tours available mornings and afternoons. Tickets must be purchased online in advance as no gate sales are available at the entrance.

Paddle or Cruise Costa Rica’s Largest Lake for Volcano Views

Eighty-five square kilometers of pristine waters stretch across Costa Rica’s largest lake, offering you unparalleled volcano views from Arenal’s base that you simply can’t experience from land.

You’ll find sit-on-top kayak tours lasting 2-3 hours that hug sheltered bays, providing stable platforms for photographing the volcanic cone’s western and southern slopes. Stand-up paddleboarding works best in wind-protected sections where you can capture mirror-like reflections during sunrise or late afternoon when light conditions are most favorable.

If you prefer less physical effort, pontoon cruises from La Fortuna and Nuevo Arenal offer panoramic perspectives during 1.5-3 hour tours. These boat tours feature cancellation policies with a 100% fee if canceled within 12 hours of departure.

December through April provides clearer skies and better summit visibility, though morning paddles year-round deliver calmer winds and smoother water conditions than afternoon sessions.

Navigate Class II-III Rapids on the Balsa River

While Lake Arenal offers serene paddling experiences, the Balsa River delivers exactly the opposite—splashy Class II-III rapids that’ll get your adrenaline pumping without requiring expert whitewater skills.

This 6-mile stretch features wave trains, small drops, and calm recovery pools perfect for first-time rafters and families with children as young as 5-8 years old.

Professional guides provide safety briefings and paddle instruction before you navigate the dam-regulated waters through lush rainforest corridors. Many guides are praised for their humor and expertise, sharing insights about local flora and fauna while ensuring everyone stays safe.

You’ll spot sloths, howler monkeys, and toucans between rapids, with swimming stops at tranquil pools.

Half-day tours from La Fortuna include hotel pickup, safety gear, and typically a Costa Rican lunch.

Expect to pay $65-85 per person for this 4-5 hour door-to-door adventure.

Rappel Down Waterfalls on Heart-Pumping Canyoning Adventures

If you’re craving an adrenaline rush that combines technical skill with natural beauty, canyoning down Arenal’s waterfalls delivers the ultimate vertical adventure. You’ll rappel 4-5 waterfalls ranging from 10-200 feet, crossing sheer drops through lush rainforest ravines with continuous water flow.

These heart-pounding tours blend waterfall rappelling, zip lines, Tarzan swings, and cliff jumps into natural pools, creating a high-intensity obstacle course.

Professional guides provide double safety systems and detailed briefings, making this beginner-friendly despite requiring no prior experience. Half-day excursions start 15-45 minutes from La Fortuna, beginning with 4×4 transfers to remote canyon access points.

You’ll experience free-hanging sections through heavy spray, controlled leaps, and natural rock chutes—positioning canyoning as Arenal’s top-tier adventure activity. The experience focuses on aesthetics and fun rather than extreme difficulty, offering spectacular canyon cliff views and up-close waterfall encounters.

Track Down Three-Toed Sloths on Dedicated Wildlife Tours

Though three-toed sloths move so slowly they’re nearly invisible to untrained eyes, dedicated wildlife tours in Arenal transform spotting these elusive creatures into a guaranteed adventure. You’ll join small groups of 6-8 participants on 2-3 hour excursions through reforested corridors and secondary forest trails where brown-throated three-toed sloths frequent Cecropia trees.

Expert naturalist guides track individual sloths’ home ranges and use high-powered spotting scopes to reveal these masters of camouflage. Tours depart at dawn and mid-afternoon when sloths are most active, taking you along flat, accessible paths through private refuges and ecological parks. Modern air-conditioned vans provide comfortable transportation between wildlife viewing stops, allowing easy access to prime sloth habitats without extensive hiking.

You’ll witness leaf-feeding behaviors, mothers carrying young, and resting sloths curled in crown foliage while guides highlight additional wildlife including toucans, howler monkeys, and diverse rainforest species.

Learn Coffee and Chocolate Production on Working Farm Tours

Beyond Arenal’s wildlife adventures, you’ll discover Costa Rica’s agricultural heritage through immersive working farm tours that transform coffee beans and cacao pods into the beverages you know and love. These 1.5–3 hour experiences at family-run farms like North Fields Café and Don Juan showcase complete “seed to cup” and “fruit to bar” production chains.

You’ll walk through coffee nurseries and cacao groves, learning how Arenal’s volcanic soils and microclimate create ideal growing conditions. Hands-on demonstrations include depulping coffee cherries, grinding roasted cacao beans on traditional stones, and preparing fresh chocolate drinks.

Tours emphasize Costa Rica’s export economy and traditional techniques, ending with guided tastings where you’ll distinguish roast levels, aroma profiles, and cacao percentages while supporting local agricultural communities. These comprehensive experiences start from $47 per person and provide an authentic taste of Costa Rican coffee and chocolate craftsmanship.

The Sum Up

You’ve got nine incredible adventures waiting in Arenal’s diverse landscape. Don’t try cramming everything into a rushed itinerary—you’ll miss the magic. Pick three to four activities that match your energy level and interests. Book ziplines and canyoning tours in advance, especially during dry season. Pack quick-dry clothes, waterproof bags, and sturdy hiking boots. Most importantly, you’ll want to stay at least three days to truly experience this volcanic wonderland without exhausting yourself.
