I have tickets for the train in May, leaving Saturday and coming back Monday. So I have Sunday to go to the market and perhaps to the valley of Montaro in the afternoon. But it sounds like I might enjoy more time in and around Huancayo. I know when I went to Colca Canyon I wouldn't have minded staying several more nights.
What does anyone think? How did you like the train, should I maybe cancel my return and take a bus back to Lima?
