I did a 4 day hike to Machu Picchu in Peru a few years ago and it was by far the best place/trip I've ever travelled to. Here is something I wrote that talks about one of the greatest moments of my life that occurred on that trip. It may sound silly, but it was quite profound. I HIGHLY recommend the experience. Go. Now.
I love it! I absolutely love it. Look at those beautiful mountains. How can you look at a picture like that and not be motivated to move! I am thinking my next trek will be to South America to visit the Galapagos, but Peru definitely is going to be a stop now. Did you hike with a group or were you alone? Was this something an inexperienced hiker could do or would it require some experience?
I did the Galapagos with my family a while back. To do it properly it's expensive but so worth it. We got on a boat that had 6 crew members and 16 people. It was such a fabulous small group and made exploring the island and learning about all the different animals so much better. We saw the massive cruise boats with groups of 100 walking around the islands or kayaking and it just looked horrible. We used Adventure Life and customized everything. They are great. But again...pricey. Let me know if you have any questions.
