Rural and chill
Calca doesn’t have a lot to offer tourists, which is part of its charm. It’s a sleepy little town with a very traditional Plaza de Armas and market. Most people in Calca are farmers, with small family plots called chacra that they walk to in the morning to work before they walk home for lunch.
If you’re interested in development work, check out the Andean Alliance for Sustainable Development, which is based in Calca.
If you are staying in the Sacred Valley, it’s worth a day to visit Calca and see how traditional it still is. This is also the starting point for most treks up Lares.
