I've mentioned before on Hubski that in 2010 my wife, myself and two of our friends went to Peru and took a 4 day hike up the Incan trail to Machu Picchu. It stands out as one of the best experiences of my life. It's a trip that I will forever measure all others against. The hike was challenging and gorgeous and the history of the trail we walked was palpable. Our guide had a dual degree in peruvian botany and history --she was PERFECT. In fact, my friend and I both had secret crushes on her. (We found out after returning home that approximately 9 months later she had a baby) -It wasn't mine... but I'm not so sure about my friend ;-)
Anyways, I want to know where I should go next that will provide a similar level of beauty, challenge, history and thrill that the trip to Machu Picchu provided? Any suggestions? Physical exertion is a must and within a 6 hour flight would be appreciated.
Thanks
