Ischigualasto National Park is one of the secrets of Argentina. Barely mentioned and hard to access, it’s rarely on the itinerary of the average traveller. It is worth the effort, though. The moonscapes turn into stunning valleys. Rocky outcrops named for the shapes they resemble (the sphinx, the submarine…) appear seemingly from nowhere.

In the rocks, hidden from view for millions of years, are the remains of dinosaurs. Many have been discovered and moved for scientific research. Undoubtedly many more remain beneath our feet. The rocks are up to 240 million years old – and this is the world’s most complete fossil record of the Triassic Era. Nowhere else on the planet reveals so much about the evolution of vertebrate life.
