Ischigualasto Provincial Park
San Juan
Ischigualasto Provincial Park, also called Valle de la Luna (Valley of the Moon), is a remarkable protected natural area located in the northeast of San Juan Province, Argentina. Covering over 60,000 hectares, the park is renowned for its unique moon-like desert landscapes shaped by wind and water erosion, featuring iconic rock formations such as The Sphynx and The Mushroom. Its arid climate and sparse vegetation create a surreal environment that captivates visitors. The park is globally significant for its paleontological value, preserving some of the world's oldest and most complete Triassic fossil records, including early dinosaurs like Herrerasaurus and Eoraptor lunensis. These fossils provide crucial insights into the evolution of dinosaurs and prehistoric ecosystems over 230 million years ago. Visitors can explore the park via guided tours on specialized vehicles, discovering geological formations like Las Coloradas cliff and the Cancha de Bochas. The site also hosts the Dr. William Sill Museum, offering scientific interpretation of its fossil heritage. The park's name, derived from indigenous languages, reflects its otherworldly and ancient character, meaning either "place where the moon alights" or "dead land." Ischigualasto's proximity to Talampaya National Park, with which it shares geological formations, adds to its ecological and scientific importance. The park's dramatic landscapes, scientific treasures, and cultural history make it a must-visit destination for nature lovers, paleontology enthusiasts, and adventurers alike.

Discounts may be available for early reservations or through local hotel packages in Valle Fértil. Prepare for strong winds and temperature fluctuations by bringing layered clothing and sun protection. Access to the park is via scenic Route RN 150, with visitor facilities and a museum at the park entrance.

Histoire
Ischigualasto Provincial Park was established on November 3, 1971, to protect its exceptional geological and paleontological heritage.
The name "Ischigualasto" originates from the extinct Cacán language, meaning "place where the moon alights" or "dead land," reflecting indigenous interpretations of the landscape.
Scientific interest began in the early 20th century, with significant fossil discoveries starting in the 1930s and accelerating after Harvard paleontologist Alfred Sherwood Romer's studies in 1958, which revealed extraordinary fossil beds.
In 2000, UNESCO designated Ischigualasto and neighboring Talampaya National Park as World Heritage Sites due to their outstanding Triassic fossil records and unique landscapes.
Over the decades, the park has become a vital center for paleontological research and conservation in Argentina.
