What Tourist Site is Worth Visiting?

My family and I are going to Peru next month and we want to visit some of the countries greatest attractions.

I see multiple places such as: Machu Picchu, Sacred Valley, Colca Canyon, a few different Monasteries but what are the MUST SEES that my family and I should visit?

You MUST see Machu Picchu. They have 4-5 day tours out of Cusco. It will be a very authentic experience, definitely great for the traveler who likes to hike. Lima is the capital and is a great, modern place to explore all that encompasses Peruvian cuisine. Arequipa has a lot of Spanish influence, and the climate is incredible there and stays the same all year long. It's sunny and a little chilly. Have fun with your family!! Should be an incredible trip!!
