Other
Wildlife

The raft hits the river and everything changes: the Petrohué becomes a traveling force, pushing and teasing, corralling you through choppy whitewater carved between black volcanic rocks. From the first bend the Andes loom like a group of slow-moving giants—Osorno’s conical flank stitched with snow and the steepled Puntiagudo poking the sky. For about two hours of active paddling you trade postcard views for the immediate work of balance, timing, and the satisfying bite of an oar taking water.

Adventure Tips

Wear secure footwear

Closed-toe water shoes or old trail runners that strap on are essential—flip-flops will come off in rapids.

Hydrate before you go

Drink water in the hours before departure and avoid heavy meals right before rafting to reduce nausea risk.

Listen closely to your guide

Commands like ‘low brace’ or ‘lean in’ are safety-critical; following them keeps the raft stable and everyone safer.

Protect electronics

Use a waterproof case or leave phones in the provided base storage; hands belong on the paddle during whitewater.

Local Insights

Wildlife

  • Andean condor (soaring above volcanic ridges)
  • Huemul deer (rarely seen in remote park valleys)

History

The river corridor was a corridor for indigenous Mapuche-Huilliche peoples and later served settlers who moved goods between lakes and fjords; the national park preserves those travel routes and volcanic landscapes.

Conservation

Vicente Pérez Rosales National Park limits infrastructure and monitors river use to protect aquatic habitats; stick to guide instructions and avoid leaving gear or trash on shore.
