Witness the Raw Power of Cerro Tronador and the Dark Ventisquero Negro Glacier
Experience the majestic power of Cerro Tronador, the highest peak in Nahuel Huapi National Park, where the sound of glaciers cracking echoes like thunder across the cordillera. This nine-hour excursion takes you deep into the heart of the Andes to witness a volcanic giant that still holds seven active glaciers. The mountain earns its name from the constant rumbling of ice, creating an atmosphere of intense natural energy that is both humbling and deeply fascinating for every visitor.
At the base of this imposing peak lies the Ventisquero Negro, a unique geological phenomenon that defies traditional expectations of glacial beauty. Unlike the bright blue or white ice found elsewhere, this glacier is dark, stained by centuries of volcanic ash that have settled into the frozen mass. This striking contrast against the surrounding mountain landscape makes it a rare sight, offering a glimpse into the complex and violent volcanic history that shaped this rugged region of the Patagonian Andes.
The tour is conducted in small groups of no more than sixteen people, ensuring a personalized experience that allows for quiet moments at the viewpoints and ample time for photography without the interference of large crowds. Your expert guide will share the geological and cultural history of the area, providing context to the dramatic scenery. If conditions are favorable, you may even spot the Andean condor, the king of the Andes, soaring gracefully above the mountain peaks.
This excursion is designed for those who wish to explore beyond the typical tourist paths and engage with the wilder side of Bariloche. By combining a visit to an inactive volcano with the observation of a rare dark glacier, the tour offers a comprehensive look at the forces of nature. It is an essential journey for anyone looking to understand the geological soul of Patagonia while enjoying the breathtaking vistas of one of the most beautiful national parks in Argentina.

Amazing views great views points. Can easily get there in any car or take a tour.

The roads in August were decent even though it’s gravel road, but they don’t tell you or indicate in the signs that some of the walks are closed (waterfalls or other glaciers, for example). You can pay the entrance to the park in cash or they let you connect to wifi and explain kindly how to buy the tickets. The open and close the one way roads on time (sharp).

The journey to black glacier is very interesting. Of the 90 some kms journey, 48 kms were on a rough, gravelled road. If you drive yourself (and not tour bus), there are several spots on the way that are out of a picture book. Several images below are from spots on the way. The black glacier in itself is not as interesting. It is a glacier that is covered with dirt a d debris and hence black. But the surrounding mountains and the lake beneath the glacier is magnificent
