Inside, a small museum has artifacts from the colonial and revolutionary periods.Besides night action, the town itself has roughly speaking no outstanding features worthy a visit. What it is really valuable of Tucumán province is nature.Nicknamed "The Garden of the Republic", it is the ideal spot for those liking hicking, horse riding or mountain climbing.If one has the guts for getting out of the hitted path, coming into the rain forest or the highest peaks it is a must. Regretably the very locals are quite unconcious about this treasure, so they are not likely to recommend it.If you have a five days available, try "La Ciudacita" the southernmost ruins of the Inca empire; you will never forget it. Guides available.
