Rafting the Futaleufú: a guide to Patagonia's legendary whitewater
Sections, rapids, season and logistics, from a lodge on the riverbank.
From the terraces at Uman Lodge you can watch the clear green Espolón River pour into the Futaleufú. Just downstream, the "Futa" narrows between granite walls and drops into Inferno Canyon, the start of some 30 miles (50 km) of whitewater that paddlers rank among the best on Earth.
If you're flying all the way to northern Patagonia to raft it, here's what you need to plan well: which trip suits you, when to go, what to pack and how to fit the river into a few days at the lodge.
Why the Futaleufú is world-class
Futaleufú means "big river" in Mapudungun, the Mapuche language. It rises in the lakes of Argentina's Los Alerces National Park, a UNESCO World Heritage Site, leaves the Amutui Quimey reservoir, crosses the Andes and runs free through Chile to Lago Yelcho.
Three things set it apart. Volume: an average flow of about 13,000 cubic feet per second (373 m³/s), squeezed through narrow granite canyons. Continuity: it drops roughly 1,000 feet (300 m) to Lago Yelcho, so the rapids keep coming. And color: the headwater lakes trap sediment, so the water arrives so clear and turquoise it looks unreal.
In 1985 an American rafting expedition was stopped by a monster rapid that has been called Terminator ever since; the first full raft descent came in 1990. In 2000 the Futa hosted the World Rafting Championship, and in 2019 the president of the International Rafting Federation called it "the best river in South America for rafting and among the top ten in the world." Since November 2025 it has also been protected by a Chilean water reserve for ecosystem preservation, one of the first two in the country.
“The best river in South America for rafting and among the top ten in the world.”

Rafting trips and difficulty
Whitewater is graded Class I to VI. Class III means real waves and maneuvering; Class IV, precise, continuous moves; Class V, long, violent rapids where mistakes carry serious consequences. These are the rafting trips Uman Lodge arranges (see Excursions):
| Trip | Distance & time | Class | Minimum age | Highlights |
|---|---|---|---|---|
| Family float · Espolón River | 5.6 mi (9 km) · 2.5–3 h | II–III | 2 | Clear water, gentle rapids, snack included |
| Bridge to Bridge (PP) | 6.8 mi (11 km) · 4.5 h | IV | 16 | About 13 rapids: Entrada, Toboggán, Mundaca, Tiburón |
| Bridge to Macal (PM) | 9.3 mi (15 km) · 5 h | V | 16 | 19 rapids, including Class V Más o Menos and Casa de Piedra |
| Azul to Bridge (AP) | 11 mi (18 km) · 6 h | V | 18 | Terminator section plus Bridge to Bridge |
| Azul to Macal · Full Day (FD) | 13.7 mi (22 km) · 8 h | V | 18 | 25 rapids, Terminator included, riverside lunch |
| Full River | 25+ mi (40+ km) · 3 days | V | 18 | Every section, riverside lunches, farewell Patagonian asado |
Every trip includes certified bilingual guides, full river gear, round-trip transfer from the lodge and accident insurance. On the Futaleufú, a safety team in kayaks and catarafts runs with each group. Rates vary by trip and season; ask when you book.
Family float on the Espolón (Class II–III)
The tributary that meets the Futaleufú below the lodge. Kids and grown-ups paddle, splash and take in the scenery, with life jacket, helmet and paddle included. There's a longer full-Espolón version (3–3.5 h) and one that pairs a gentle stretch of the Futa with a walk in the Futaleufú National Reserve (about 5 h).
Bridge to Bridge (Class IV)
The classic run. Earth River, the outfitter behind the first raft descent, estimates it accounts for more than 90% of commercial rafting on the river. The action starts almost at once with Entrada, Toboggán, Pillow, Magic Carpet, The Bull and Mundaca (IV+), the section's signature rapid, followed by Pudú, Puma, Güiña, Cóndor and Tiburón, named after threatened Chilean wildlife.
Bridge to Macal: Más o Menos and Casa de Piedra (Class V)
Bridge to Bridge, extended downstream: Más o Menos ("more or less"), long and powerful, and Casa de Piedra, named after a 50-foot (15 m) boulder in midstream. Then the Class III Macal section opens up to glacier-capped views.
Azul to Bridge and Azul to Macal: the Terminator section (Class V)
You launch on the glacial Río Azul and, once on the Futa, meet Asleep at the Wheel and Terminator: close to a mile (1.5 km) long including the entrance, threaded between house-size granite boulders. Guides stop to scout it, and a trail lets you walk around if you'd rather. Khyber Pass and Himalayas, the river's biggest wave train, follow. Azul to Bridge ends at the bottom of Bridge to Bridge; Azul to Macal (Full Day) carries on to Macal, with lunch on the riverbank. Many guides call it the best day of rafting on the planet.
Inferno Canyon, Zeta and Throne Room (Class V and V+)
The river's wildest stretch begins right by the lodge. Inferno Canyon strings five rapids between sheer walls and isn't part of the regular trips. Further down, Zeta and Throne Room (V+) are portaged by every commercial outfitter: you watch from the canyon rim.
Which trip is right for you?
- Families with young kids: the Espolón family float, from age 2. Add the canopy zipline (six lines over native forest, minutes from town) or the float-and-hike combo.
- First-timers in good shape: Bridge to Bridge, from 16. No experience needed, but you must be able to swim: this is genuine big-water Class IV, not a lazy float.
- First-timers who want more: Bridge to Macal adds Más o Menos and Casa de Piedra to the same morning.
- Experienced or adventurous rafters: Azul to Bridge (6 h) or, if you only have one day, Azul to Macal · Full Day (8 h), from 18.
- Whitewater pilgrims: Full River, three days on every section with riverside lunches and an asado to finish. Lodging isn't included.
- Not sure? Do Bridge to Bridge first, then decide with your guide whether to go for the Full Day.
Best time to raft the Futaleufú
The outfitter runs trips October through April, and the most reliable stretch is December through March, the Southern Hemisphere summer, so Christmas and New Year fall in high season. Uman Lodge is open November 7 to March 31.
- November–December: higher water from snowmelt; Terminator can close on some days. Holiday weeks book up first.
- January: stable levels, every section open. Daytime highs often reach the mid-70s to 80s °F (24–29 °C).
- February: many guides' favorite: typically the driest, sunniest weeks.
- March: similar water, fewer people, shorter days.
Flows depend on dam releases in Argentina and on the tributaries, so guides check the level every morning and each section has its own cutoff. The weather can change fast even in summer, and the water is always cold.
A rafting day from Uman Lodge
Here's how a Bridge to Bridge or Full Day trip runs from the lodge:
- Breakfast at the lodge, swimsuit on, towel and a base layer in your bag.
- Included transfer
- Gear-up and safety talk. Wetsuit, helmet, life jacket and paddle. Guides cover commands and swimming position, then you practice before the first rapid.
- On the river. Each raft has a certified guide, backed by safety kayakers and a rescue cataraft, standard practice on the Futa.
- Snack or lunch. Half-day trips include a snack; the Full Day includes lunch on the riverbank.
- Back at the lodge. After Bridge to Bridge, the afternoon is yours for the spa: sauna, hammam, hot tub and pools. After the Full Day, a shower and the hot tub before dinner.
- Dinner at Uman Gourmet (dining), looking over the valley you paddled.
Each departure needs at least four paddlers, so book your trip when you book your suite, especially for January and February.
What to pack and what's provided
Provided: certified bilingual guides, safety kayakers and cataraft, full river gear (wetsuit, life jacket, helmet, paddle), round-trip transfer, snack or lunch depending on the trip, and accident insurance.

Getting here and a sample 3-night plan
Futaleufú is remote, which is part of the point. From the US, Canada or the UK, plan on the better part of two days each way. Full details on Getting Here.
- Via Santiago, Chile: fly to Santiago (SCL), then about 1.5 hours to Puerto Montt (PMC). Small planes (Aerocord or Pewen) fly from Puerto Montt's La Paloma airfield to Chaitén, then it's about 93 miles (150 km) by road; Aerocord also runs charters to Futaleufú's airstrip, 2 miles (3 km) from the lodge.
- Via Buenos Aires, Argentina: fly to Esquel (Aerolíneas Argentinas), then drive 61 miles (98 km) across the Futaleufú border crossing. US, Canadian and UK passport holders currently don't need a tourist visa for Chile or Argentina, but check before you travel.
- Overland: see our Carretera Austral guide.
For paddlers (3 nights):
- Day 1 · Arrive. Settle into your suite, spa, quiet dinner.
- Day 2 · Bridge to Bridge. Morning on the river, lunch at the lodge, a free afternoon.
- Day 3 · Full Day. Azul to Macal, from Terminator to the Macal valley, with a riverside lunch. Or slow down with fly fishing or a ride.
- Day 4 · Depart. After breakfast, back to Esquel or Chaitén, or south on the Carretera Austral.
With kids: Espolón float on day 2, canopy or horseback riding on day 3; teens 16 and up can add Bridge to Bridge. If you can, add a buffer night in case high water means switching sections.
