Below the Rapids: Tenorio’s Cascabel Drop and the Two-Hour Rush
Two hours, 22 rapids, one 12-foot finale — a rainforest rush that finishes with a Casado
By the time the guide gives the first command — paddle forward — the river has already set the tone. The Tenorio does not whisper; it dares. Green walls of rainforest close in, wet air presses at your temples, and every bend seems set to rearrange the day. For two hours you trade the predictable rhythm of trail for the unpredictable cadence of moving water: a dozen-and-change rapids that alternate between teeth-clattering swells and sudden calm where kingfishers hover like punctuation marks. The trip finishes with a small, uncanny moment of theater — Cascabel Falls, a 12-foot drop that kicks free the last of your breath and, depending on your paddling, your grin.
Trail Wisdom
Arrive Hydrated
Start the day well-hydrated; you’ll sweat on the river and the guides won’t let you drink from the river itself.
Secure Footwear
Wear closed, grippy water shoes or old trail runners that stay on during swims and protect toes on rocky exits.
Listen to the Guide
Follow commands immediately — synchronized paddling and bracing are how the raft gets through big rapids safely.
Pack a Small Waterproof Camera
A compact action camera on a head strap or chest mount captures the drops without risking your phone.

Conservation Note
Operators emphasize low-impact access and river stewardship; follow leave-no-trace principles and avoid disturbing riverbanks to protect fragile riparian habitat.
The Tenorio corridor has long supported local farming communities; in recent decades river-based tourism has become an important economic lifeline for towns like Cañas.
Seasonal Guide
spring
Best for: Lower river flow, Stable weather windows
Challenges: Warmer temperatures, Occasional shoulder rains
Spring (Mar–May) often marks the end of the dry season with manageable flows and stable weather—good for calmer rapids and wildlife along the banks.
summer
Best for: Higher water levels, Stronger rapids, Lush jungle scenery
Challenges: Shorter daylight, Intermittent heavy rain
Summer (Jun–Aug) brings rising water and more powerful Class IV moments; expect a wetter day and epic waves.
fall
Best for: Peak river volume, Big-rapids experience
Challenges: Higher chance of cancellations, Slippery trails and muddy access
Fall (Sep–Nov) is the wettest period; rapids feel bigger but tours can be curtailed for safety during storms.
winter
Best for: Dry-season access, Stable roads and weather, Post-trip sightseeing
Challenges: Lower flow in some sections, Warmer midday temperatures
Winter (Dec–Feb) aligns with Costa Rica's dry season—roads are reliable and the run is comfortable, though some waves may be smaller.

Common Questions
How hard are the rapids?
The run includes class III–IV rapids: technical but guided, suitable for adventurous beginners who follow instructions; expect solid waves and occasional technical maneuvers.
Is there an age limit or minimum experience required?
Policies vary by operator, but generally guests should be at least 12 and able to follow guide instructions; check with the operator for exact age and health restrictions.
What happens if I fall out of the raft?
Guides are trained in river rescue and will organize an on-water recovery; you’ll be coached to float on your back with feet downstream and wait for guidance.
Can I bring a phone or camera?
Small waterproof cameras or action cams are fine when secured; phones should be in waterproof cases or left at the base with staff.
How long is the drive to the river from Tamarindo?
Drive times vary by pick-up; from Tamarindo expect roughly 1.5–2.5 hours depending on traffic and exact operator routing.
Are meals included?
Yes — a traditional Costa Rican Casado lunch is included at the tour base and can usually be adapted for common dietary needs.
What to Pack
Water shoes (secure footing), quick-dry clothing (comfort), waterproof camera or case (memories), light snack and electrolytes (energy)

Quick Travel Tips
1) Book morning departures to avoid afternoon storms; 2) Confirm pickup location in Cañas or Tamarindo the night before; 3) Leave valuables at base or in vehicle; 4) Bring cash for tips and small purchases.
Local Flavor
After the run, dig into a Casado at the tour base — rice, beans, plantains, and grilled protein — and try a local soda (family-run eatery) in Cañas for coffee and fresh fruit juices before heading back to town.

Closest airport: Daniel Oduber Quirós International Airport (LIR, Liberia) — ~1–1.5 hour drive; Driving: expect 1–2 hours from Tamarindo depending on routing; Cell service: intermittent along the river, reliable at base; Permits: none required for this commercial rafting run.
Sustainability Note
This run relies on healthy river corridors — minimize plastic use, stay on established exits, and choose operators that invest in local conservation and community programs.
