After spending a restorative couple of hours in Aguas Calientes, we took the train back to Cuzco and woke up very early to catch a bus to Puno.
One thing I wish I would have done during this trip to Peru was to have taken notes during our tours or written in a journal at the end of each day. We learned so much about the history and culture from various tour guides (and most of that information is not readily available on the internet).
We pieced together this three week trip as we went along and it was extremely exhausting at times, but we sure covered a lot of ground. There are so many little details about places we visited that I just cannot remember. So take my advice, if you want to retell the stories with accuracy or make a scrapbook of your journey, keep a journal, record things with your phone, take pictures of interpretive signs – whatever you need to do to remember the details.
