Four long hours south of Ayacucho on winding, unpaved roads is the former Inca provincial capital of Vilcashuamán, set where the north–south Inca highway crossed the east–west trade road from Cusco to the Pacific. You can still see the Templo del Sol y la Luna and a five-tiered platform, known as the Ushno, crowned by an Inca throne and surrounded by stepped fields once farmed by Inca. An hour's walk from Vilcashuamán (or a half-hour's walk south past the main road from Ayacucho) is Intihuatana, where Inca ruins include a palace and tower beside a lagoon. Former Inca baths, a sun temple, and a sacrificial altar are also on the grounds. Check out the unusual 13-angled boulder, one of the odd building rocks that are an Inca hallmark. Ayacucho travel agencies can organize tours of both sites (S/90), or you can catch a bus or colectivo for S/15-20. Ask around to confirm where these public transport options are leaving from, as pickup points change frequently.
