Known as the 'Valley of the Moon,' the park has been a UNESCO World Heritage Site since 2000, famous for its Triassic geological formations dating back 280 million years and containing key fossils for understanding the evolution of life.

The best season is during the Southern Hemisphere winter (June to September), when temperatures are cooler, between 10°C and 20°C, avoiding the intense summer heat. As for the time of day, choose the morning to make the most of the natural light and avoid crowds; check the forecast, as strong winds can occur.
Access is limited due to the rocky and uneven terrain; the safari off-road vehicles are mandatory, but there are no ramps or paved trails for wheelchairs. It is recommended to ask in advance about adapted options or special tours; contact the park at +54 264 497-0040 for more information.
