Natural sculptures ascend to an altitude of up to 160 metres (525 feet) with curious shapes that have triggered their names: El Rey Mago (the wise man), Las Catedrales (the Cathedrals) and El Castillo (the Castle). This is the only area in the world known to hold a complete sequence of continental sediments with abundant fossil flora and fauna of the Triassic Period. Wild guanacos, hares, armadillos and foxes wander in the park and condors and eagles can be seen overflying the area.

Together with Valle de la Luna National Park (in the neighbouring San Juan Province and only 10 km -6 miles- away) Talampaya National Park was declared a UNESCO World Heritage Site.
