Visit the Petrified Forest

Walking among 150-million-year-old fossilized trees at the Petrified Forest reveals a landscape older and more surreal than the glacial scenery near Lago Nahuel Huapi (rank 6). Individual logs measure up to 30 meters in length, with some trunks still bearing bark impressions that date back to the Jurassic. A 2025 geotourism study recorded 75,000 annual visitors, a number that is 40% lower than the whale-watching crowds at Peninsula Valdes, ensuring a tranquil experience.
