Machi Picchu was one of the few items on my world travels bucket list that was actually more spectacular and awe-inspiring than expected. Many famous landmarks are nice but kinda just ok when you are up close. Machi Picchu is a whole other category. The trip to get there is a journey itself whether you trek or take the scenic train from Cusco.
I tell all my friends that if they only go to one major world landmark before they die, Machu Picchu is a good choice.
