Every year, hundreds of thousands of Americans land in Costa Rica and ask the same question: what are the best things to do in Arenal Costa Rica? It is the right question — because the Arenal Volcano region around La Fortuna is the single most activity-rich destination in the entire country. Within a 30-mile radius of this small town, you can hike an active volcano at sunrise, swim beneath a 70-metre waterfall, soak in natural geothermal hot springs at dusk, white-water raft a Class III river, spot sloths in the rainforest canopy, and zip-line above the jungle at treetop level — all in the same 48 hours. This guide answers that question definitively, with Ecoterra Costa Rica’s local expertise built into every recommendation.

No list of La Fortuna things to do in Arenal volcano Costa Rica is complete without the La Fortuna Waterfall. This 70-metre cascade drops into a natural pool surrounded by primary rainforest — the descent via 500 steps takes 15–20 minutes and rewards you with one of the most photographed natural scenes in Central America. Swimming in the ice-cold pool at the base is permitted and genuinely thrilling. Entrance is approximately $18 USD. Ecoterra’s guided waterfall tours depart at 7:30 AM for optimal light, wildlife sightings along the trail, and crowd-free access.
Arenal Volcano towers at 1,670 metres and is one of Costa Rica’s most active geological features. Guided hikes through the El Silencio Reserve and Arenal Volcano National Park traverse hardened lava fields, old-growth rainforest, and open-sky viewpoints with direct volcano sightlines on clear mornings. Early departure (7:30 AM) is essential — cloud cover builds by mid-morning regardless of season. Ecoterra’s certified naturalist guides provide geological and ecological context that transforms a hike into a genuinely educational encounter.
After a full day of active touring, geothermal hot springs are the definitive Arenal ritual. Heated naturally by Arenal Volcano’s underground thermal activity, the springs maintain temperatures between 98–104°F — perfect for muscle recovery and stargazing. Multiple natural hot spring sites are accessible from La Fortuna, ranging from free riverside pools to full-facility thermal resorts. Ecoterra coordinates evening hot spring visits as standalone bookings or as part of full-day combo packages.
The Arenal region hosts over 500 bird species and dozens of mammal species including two and three-toed sloths, howler and white-faced capuchin monkeys, toucans, motmots, and green basilisk lizards. Ecoterra’s wildlife tours use professional spotting scopes that bring canopy-level sloths into extraordinary detail — a qualitatively different experience from standard binocular observation. Morning departures (6:30 AM) maximise encounter frequency during peak activity hours.
For US travellers seeking an adrenaline hit, Arenal’s river systems deliver Class II–IV white-water rafting through spectacular jungle gorges. The Sarapiquí River suits beginners and families; the Toro River offers more technical Class III–IV rapids for experienced paddlers. All Ecoterra rafting tours include certified safety guides, helmets, life jackets, and riverside lunch. No prior experience required for most tours.
“In Arenal, the hardest decision is not what to do — it is how to fit everything into the days you have.” — Ecoterra Local Guide

| Transition 🌤 | May – Jun | 71–86°F | Waterfall (building flow), wildlife tours | Low — great value |
