Aconcagua climbing permit
The office for the climbing permit on Aconcagua is on Visitors Center (Subsecretaria de Turismo), sited in 1143 rd San Martin Ave., Mendoza City. You will need to fill in the registration form online first of all and this is then countersigned by our local agent. On arrival in Mendoza we take the signed form to a local Government cashier and pay the required fee for the permit in local currency pesos. Having got the receipt, we then take the form to the visitors centre and the Aconcagua park office where they will hand out the actual permit.
The office is open 8am to 6pm Monday to Friday, but only 9am to 1pm on weekends. The validity of the permit is 20 days for a full ascent, which starts from the date you enter the park.
Prices do change year to year and are also dependent on the season. You can check the current prices at aconcagua.mendoza.gov.ar
