The best and cheapest way to visit Ingapirca the best preserved Inca ruins of Ecuador from Cuenca is with the bus. You need to go to the main terminal and take a “Canar” bus. It cost me $5 there and back. But it took ages since the bus stops for everybody who waits for a bus at the streets. In total it took about 3h there then I only had 45min to visit the ruins and the museum and then the same exhausting trip for 3h back. Ingapirca cost $6 entry for foreigners. The ruins are nice but not to compare with Machu Pichu or the Mexican pyramids. Still it was worth seeing! If I would have done that trip with a tour it would have cost me about $40. So $11 is a great deal I think.
