Stayed here a few days back.
Ollantytambo is the only remaining Inca village in the region with 100% cobbled streets and the original irrigation channels in the middle of each street.
In Ollantytambo these irrigation channels are fully functioning, gushing full of fresh mountain water carrying it round and down on its way to the Urumbamba below.
Every other town has filled these channels in to make way for more roads and more traffic.
For this reason Ollantytambo retains a charm you won’t find in other Peruvian towns.
