Carara Adventure Park

Arenal Eco Tours is a family-run outfit born and raised in the shadow of the Arenal Volcano. Founded in 2009 by lifelong La Fortuna residents, the company grew from a single guide with a pickup truck into a tight team of certified local naturalists who still lead nearly every departure themselves. They know which trail the howler monkeys favor at dawn, where the volcano shows its best face at dusk, and how the seasons quietly reshape the rainforest from one month to the next.

​

Groups stay small on purpose — usually no more than ten to twelve travelers — so guides can slow down, point out the things you'd never spot alone, and answer the questions that make a walk feel like a private masterclass in Arenal's ecology. Every guide carries ICT certification and wilderness-first-aid training, and safety briefings are never skipped, whether you're soaking in the Tabacón hot springs or rappelling beside La Fortuna Waterfall.

​

Sustainability isn't a tagline here; it's how the business stays in business. Arenal Eco Tours keeps group sizes light on the land, partners with neighboring farms and family-run sodas for meals, and reinvests in local conservation and reforestation around the lake. That commitment — and a track record of consistently delighted travelers — is exactly why Arenal Eco Tours was vetted and verified in person by the Vector Journeys team.
