Te dejo la traducción al inglés británico, manteniendo un tono turístico, aventurero y natural para una guía o libro de viajes:

Have you ever dreamed of walking through a Martian landscape without leaving Earth? If the answer is yes, pack your bags because Sierra de las Quijadas National Park, in the north-west of San Luis Province, is exactly what you’re looking for.

This hidden gem of Argentina’s geography welcomes you with immense clay-red cliffs, deep ravines carved by wind and water over millions of years, and a mystical energy you can almost feel in the air. It’s not just a place to take spectacular photographs; it’s a journey back in time to the age of the dinosaurs.

What makes it so special?

The park’s undisputed highlight is Potrero de la Aguada, an impressive natural amphitheatre surrounded by rock walls rising more than 200 metres high. As the sun begins to set, the play of light and shadow across the reddish stone creates a breathtaking visual spectacle.

Beyond its scenic beauty, Sierra de las Quijadas is also an archaeological and palaeontological site of enormous importance. Fossils of unique pterosaurs (flying reptiles) have been discovered here, along with remains of settlements belonging to the native Huarpe peoples.

Trails for every kind of traveller

The park adapts to whatever kind of experience you’re after. You can enjoy short self-guided walks to spectacular viewpoints or, if you have a more adventurous spirit, hire a local guide and descend into the canyon itself. Whichever option you choose, the feeling of vastness is guaranteed.

Tips: Bring plenty of water (at least 2 litres per person), as there is no drinking water or shops inside the park; wear closed footwear with good grip, sunscreen, a hat and sunglasses; there is little to no mobile signal throughout most of the park, so download maps before you go; respect the wildlife and take all rubbish with you; let’s help preserve this natural sanctuary.
