ah this brought back memories I was there 13 years ago, I done the Salkantay trek and we stayed for 2 nights in Aguas Calientes, I do remember it being beautiful and I was very happy to go in the hot bath after trekking for 6 days.And that train journey back to Cusco was amazing too. Actually the trek was awesome, the mountains are magnificent we camped in front of a Glacier one night, that was amazing, fecking cold but.
