Awesome trip. A once in a lifetime experience. Great trek. Definitely need to be fit to walk up and down mountains for 10 kilometers a day for 4 days.
But felt huge achievement when finally reaching Machu Picchu. I'd recommend this trek and with this company every time. The sights and scenery are pretty hard to beat anywhere else in the world. It's not just the hiking that will take your breath away. The guide and porters we're outstanding.
Make sure you bring your camera to capture the moments as there is so much to take in. Worth ever penny.
