Which national park in Argentina is known for its red rock formations and fossilized trees? Talampaya National Park is the answer.

Talampaya National Park lies in La Rioja Province in western Argentina. It is famous for towering red sandstone walls, canyons and wind- and water-sculpted formations, while its fossil-bearing rocks preserve evidence of plants and animals from the Triassic Period, including fossilized wood and tree remains in the wider paleontological landscape.

The park forms part of the Ischigualasto–Talampaya natural area, which records roughly 50 million years of Triassic geological history. That record helps scientists trace the transition from mammal-like reptiles toward the early dinosaurs. The nearby Ischigualasto Provincial Park is especially associated with the nickname “Valley of the Moon,” so the two parks are often confused.

Talampaya also preserves ancient human traces: petroglyphs were carved into canyon walls and sheltered rock surfaces centuries before European contact. The area became a provincial reserve in 1975, a national park in 1997 and a UNESCO World Heritage Site jointly with Ischigualasto in 2000.
