Abdón Castro Tolay is a rural municipality and village in the Cochinoca department in Jujuy Province in Argentina.

Abdón Castro Tolay, formerly Barrancas, is a place of enormous natural walls that preserve cave paintings and petroglyphs.

The town, which bears the name of a teacher who dedicated his life to the community, is on provincial route RP 75.

There is a garment making spinning mill and regional products, which have revived the previously paralyzed economy.

Before, a cooperative of artisans provided blankets to schools in la Puna, a project which sees the active participation of families from other Jujuy towns.
