Luego de instalarnos en nuestro alojamiento saldremos en dirección a la Reserva Natural Sierras Grandes donde realizaremos un trekking de exigencia media para llegar a las cuevas donde podremos apreciar el arte rupestre, huella de los primeros pobladores de la zona.  Al finalizar esta actividad regresaremos al hostel para descansar y disfrutar de la paz y armonía de las sierras.

We will begin our third day early, because after breakfast we will depart to target the Ernesto Tornquist Provincial Park, specifically to the Sector Base of the Hill Window. We will trek that we will be invited to walk a path towards a point, in which far from complete our journey, the nature present us with one of his masterpieces: The window or Cashuatí (1100 m.s.n.m.) as the name given by the indigenous people, where we will start a spiritual journey that will invite us to contemplate the vastness and simplicity of the things that surround us.

Our fourth day will be spent to make a great adventure: climb to the top of the Hill, Three Peaks, the highest point of the province of Buenos Aires with 1239 metres of height above the level of the sea; to complete this feat, we will trek for demanding high that will take us most of the day.
