Getting there & away
To reach Altamira, you can take any bus that runs between San Isidro and San Vito and get off in the town of Guácimo (often called Las Tablas). From Guácimo buses depart at noon and 5pm daily and travel the 16km to the town of El Carmen; and if the road conditions permit, they continue 4km to the village of Altamira. To return to Guácimo, buses depart from Altamira at 5am and 2:30pm daily. From the village of Altamira, follow the Minae sign (near the church) leading to the steep 2km hike to the ranger station.
Vehicles with 4WD go all the way to Altamira station. In theory, it is possible to hire a 4WD taxi to bring you here, either from San Vito or Buenos Aires. Keep in mind, however, that the roads are grueling, and bad conditions can make it pretty tough for anyone. If you are driving here, inquire about road conditions prior to your departure.
