Barrancas (also known as Abdón Castro Tolay) is a small village in the Puna of the province of Jujuy, Argentina. It is located in the department of Cochinoca, approximately 175–180 km from San Salvador de Jujuy and about 50 km from the Salinas Grandes, at an altitude of approximately 3,600–3,643 meters.
The village has only 300–350 inhabitants and is named after the imposing volcanic cliffs (barrancas/farallones) that surround it.
The site is primarily known for its rich archaeological heritage: one of the most important collections of rock carvings and petroglyphs (pre-Inca and Inca) in Argentina, with traces of human presence dating back as far as 10,000 years.
Major attractions include the Reserva Municipal Natural y Cultural and the Centro de Interpretación Arqueológica (opened in 2020).
Historically, it was situated on a branch of the Camino del Inca.
In 1919, the current village was founded around a school that Master Abdón Castro Tolay relocated there.
The local economy revolves primarily around the farming of llamas and sheep, with traditional Andean culture and cuisine (including llama and lamb meat, corn, and potatoes).
It is a destination for rural and cultural tourism and was a candidate for the UN's Best Tourism Villages in 2024.
