Updated for 2026 – Verified Travel Guide by Raul Silva M. About the Author

Petrohué Waterfalls is one of the most visited natural attractions in Chile's Los Lagos Region. Located within Vicente Pérez Rosales National Park—the country's oldest national park, established in 1926—these striking waterfalls are formed by the Petrohué River as it rushes over volcanic basalt shaped by ancient eruptions of Osorno Volcano.

Visitors can explore a network of well-maintained walkways and viewpoints offering spectacular views of the emerald-colored water, surrounding native forest, and nearby volcanoes. The Petrohué River originates at Lake Todos los Santos and flows westward toward the Reloncaví Estuary, creating one of the most scenic landscapes in southern Chile.

With opportunities for hiking, rafting, kayaking, photography, wildlife observation, and sightseeing, Petrohué is an ideal destination for travelers seeking both natural beauty and outdoor adventure in Chilean Patagonia.


Best Time to Visit Petrohué Waterfalls

The best time to visit Petrohué Waterfalls is during the Southern Hemisphere summer, from December through March. During these months, temperatures are generally mild and pleasant, making it ideal for walking the trails, enjoying the viewpoints, and exploring other attractions in Vicente Pérez Rosales National Park.

The Los Lagos Region has a temperate oceanic climate characterized by abundant rainfall throughout much of the year. Average summer temperatures typically range from 10°C to 25°C (50°F to 77°F), while winters are cooler, wetter, and often cloudy. The lush forests and evergreen vegetation surrounding the waterfalls thrive because of this consistently humid environment.

Although January, February, and March are usually the driest months, Petrohué Waterfalls can be visited year-round. During winter, particularly from June to August, increased rainfall and snowmelt often boost the flow of the Petrohué River, creating a more powerful and dramatic display. Visitors seeking the best weather generally prefer summer, while those interested in seeing the falls at their most impressive may enjoy the wetter months.


The River and Its Surroundings

The Petrohué River originated through a combination of glacial retreat and volcanic activity that shaped much of southern Chile. Ancient geological processes transformed what was once a larger body of water into two separate lakes: Lake Llanquihue and Lake Todos los Santos. Today, the Petrohué River serves as the natural outlet of Lake Todos los Santos, creating one of the most scenic waterways in the Los Lagos Region.

The famous Petrohué Waterfalls were formed when volcanic eruptions deposited layers of basaltic lava across the river's path. Over time, the river carved channels through this volcanic rock, creating the rapids and cascades seen today. The striking contrast between the dark lava formations and the river's turquoise waters is one of the area's most distinctive features.

The surrounding landscape is characterized by evergreen forests, abundant rainfall, and views of nearby volcanoes, including Osorno Volcano. These conditions support a rich ecosystem that attracts nature lovers, photographers, hikers, and outdoor enthusiasts throughout the year.

Many visitors reach Petrohué on day trips from Puerto Montt, Puerto Varas, or Osorno. The waterfalls are also a popular stop for travelers following the scenic route between Chile and the Argentine city of San Carlos de Bariloche.
