You hit the muddy farm track at dawn and the Arenal cone looms ahead—black flank rising above pastures and stands of secondary rainforest. The ATVs rumble through cattle roads and switchbacks, dust throwing sparks in the morning light, then after lunch the river waits: water churning, waves punching, the current daring you to stay calm.

You hit the muddy farm track at dawn and the Arenal cone looms ahead—black flank rising above pastures and stands of secondary rainforest. The ATVs rumble through cattle roads and switchbacks, dust throwing sparks in the morning light, then after lunch the river waits: water churning, waves punching, the current daring you to stay calm.
Arenal is a young volcanic complex (its last major eruption was in the 1960s–70s), its slopes formed by andesitic lava and ash that shape steep ridgelines and fertile plains. La Fortuna grew as an agricultural and ranching hub; today tour operations thread through private farms and plantations that trace that working landscape. The river you’ll run cuts through valley fill and volcanic soils, offering a high-energy mix of Class III–IV rapids in an 11 km (≈7 mi) section with more than 30 named drops.
Expect about 28 km (17 mi) on modern ATVs over mixed terrain—mud, gravel, pasture—and roughly 11 km of guided rafting where helmets, life jackets and a safety briefing are standard. The combo is adrenaline-forward but accessible: operators include transportation, lunch, snacks and bottled water. Bring quick-dry layers, secure footwear, and a towel; drivers need a valid license for the ATV portion and participants should be comfortable in moving water.
Plan for 6–8 hours total, mid-morning starts to avoid heat and heavier afternoon rains in the wet season. Hydrate, confirm weight and pickup details when booking, and arrive with a sense of play—this is an expedition that alternates grunt and grin, granular terrain and whitewater that won’t let you walk away dry.

La Fortuna and the Arenal area were reshaped by volcanic activity in the 20th century; agriculture and ranching on volcanic soils led to the private tracks you’ll traverse today.
Operators often work with private landowners; follow Leave No Trace practices, avoid single-use plastics when possible, and respect local farm operations to minimize impact.
