The raft drops into the Sarapiquí and the river immediately takes the lead: boiling boils, hollow waves and rocky teeth that demand attention. For two hours the current runs a relentless gauntlet of Class III and IV rapids, splashing through low rainforest cliffs and past emergent trees where toucans call and howler monkeys keep time.

The raft drops into the Sarapiquí and the river immediately takes the lead: boiling boils, hollow waves and rocky teeth that demand attention. For two hours the current runs a relentless gauntlet of Class III and IV rapids, splashing through low rainforest cliffs and past emergent trees where toucans call and howler monkeys keep time.
Geology here is recent — volcanic soils and uplifted alluvium feed the channel with coarse boulders and sudden constrictions that create the powerful hydraulics boaters face. The river corridor sits inside a larger protected landscape: the Sarapiquí basin links to La Selva Biological Station, one of Costa Rica’s most important tropical research sites, and the stretch is officially recognized as a natural monument for its ecological and cultural value.
Culturally, guides mix bilingual safety instruction with local knowledge: you’ll hear about cacao farms upriver, small river communities and how ecotourism supports conservation and research.
Practically, expect a full outing from La Fortuna — about 5 hours door-to-door with roughly two hours on the water. Operators provide helmets, PFDs, a safety kayaker and a post-trip Casado lunch. This run is demanding: guides will need paddlers to work as a unit through powerful eddies and boily drops. Bring closed-toe water shoes, quick-dry layers, sun protection and a sense of teamwork. Stay hydrated and follow the guide’s instructions; the Sarapiquí is exuberant but unforgiving if you underestimate it.
Expect a high-intensity outing: two hours of continuous Class III–IV rapids that require strong paddling, quick reactions and sustained core engagement.
Previous rafting experience helps but isn’t mandatory — guides will train teams, though strong swimming skills and fitness are required.
Most operators include hotel pick-up (within a local radius), helmets, PFDs, safety kayaker support, bottled water, fruit on the river and a traditional Casado lunch.
Minimum age is typically 12; many operators enforce a maximum weight around 120 kg (260 lb) and may refuse participants with certain medical conditions.
Arenal Rafting operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
