Cusco Museums
Cusco’s museums have stiff competition with the incredible richness you find in the outdoor archeological sites. However, on your first day at altitude, taking it easy at a museum is a good way to acclimate. Visiting Cusco between November and March will likely get you a rainy day perfect for museums.
If you have time for two, visit Qorikancha for the mix of Inca and Colonial cultures and Museo de Arte Precolombino for art from around Peru.
If you want to learn something but for it to be fun and interactive, go to the Traditional Textile Center of Cusco where you can learn about how to dye wool with natural materials and how to make yarn and weave traditional patterns.
