We did the Inca trail (4D/3N) tour. The landscape is absolutely beautiful and very diverse. Some level of fitness is necessary but it is not the most challenging hike.
The tour people took really good care of us. The chef Alex prepared multi-course meals for all three meals of the day. My wife is vegetarian so he also made a vegetarian version of each dish for us.
Our guides Ronald and Richard were extremely friendly and made sure everyone in the group is well taken care of. There are stops at historic sites along the way and the guides will give you some information about the significance of the site.

The equipment provided by the tour (tent, therm-a-rest, etc) were in good shape. We had our own sleeping bags though.
There washrooms in some of the camp sites and the tour provides a portable potty in other places.
Machu Picchu is interesting but also very very busy. I personally enjoyed other sites on the trail more. Keep in mind if you want that perfect instagram photo you have to wake up very early on the fourth day and RUN as soon as they open the gates.

My wife and I completed the 4D/3N trek yesterday and both thought it was truly amazing. Here are a few aspects which made this experience unforgettable:
Porters - absolute heroes. They carried our entire camp on their backs, and had everything set up upon our arrival every lunch and dinner time. They even applauded us when we left camp and when we arrived again. Sounds cheesy but it was great fun.
Food - wow. Wow wow wow. How our chef and sous chef cooked such incredible cuisine on a camp stove I will never know. Magicians. And there was always more than enough.
Guides - Jaime and Marizol were awesome. Jaime knew everything about the Incas, Peru and its history, local wildlife, machu picchu, and basically everything we asked him. All explained in faultless English and with great enthusiasm. His love for Peru, his job and alpaca expeditions is very clear. He was always really cheerful, friendly and professional. Marizol was fantastic at keeping morale up on the harder sections and also incredibly knowledgeable about the Incas and their empire. I really couldn't have asked for a better pair of guides.
Pace - our team was generally pretty quick (the original superhikers) but you can take it at your own pace. There's no pressure to go faster than you can, and no problem if you want to shoot off in front.
Overall this was one of the best experiences of my life. The scenery and trail are amazing, but the professionalism, efficiency and tireless effort of our alpaca team allowed us to enjoy it to the absolute fullest. Thank you Marizol and thank you Jaime!

I've wanted to see Machu Picchu for a really long time, and when planning our trip spent a while researching which company to go with. I found alpaca through trip advisor and am so pleased I trusted their many fantastic reviews.
I was apprehensive before going about the walking distances and difficulties but during the trek felt there was no pressure to rush, and was supported by the guides and my fantastic team. The trek was hard but it would have been harder without such a supportive and caring group.
Our guides - Jaime and Marizol were knowledgeable, funny and attentive. They shared so much interesting information about Peru, the Incas, nature and the areas we were trekking through. Marizol kept us going throughout the whole trek with her encouragement to the "SUPERHIKERS" and Jaime was fantastic at recommending the best spots for photographs and breaks.
We were the third group up to sun gate on the final morning, and he found us the most amazing place to watch the fog disappear over Machu Picchu which was truly magical.
The porters and chefs are also incredible. Carrying 20kg and completing the Inca trail just ahead of us so that they could prepare our lunch, dinner and campsite each day. Every evening we arrived to a fully set-up campsite, a hot bowl of water to wash with and tea, coffee and snacks. As a fussy eater I was worried about what I would eat throughout the trip but the food was amazing - lots of options, lots of variety and lots of food. The chef even managed to bake a cake on our final evening, where we camped on the border of the Amazonian rainforest and the Andes mountain range. I can barely bake a cake in my kitchen, in my house!
Alpaca Expeditions pride themselves on providing a fair working environment, a fair wage and being environmentally friendly which just makes this company even better.
From the briefing meeting the evening before we left, to being dropped at my hostel the trip was so well organised. I felt valued and safe, and Jaime and Marizol really did make this an unforgettable experience.
Also we were so lucky with our group - 12 of us altogether, some Canadian, some American, some Welsh and some English. I feel like I've made some friends for life, and shared an amazing journey with them.
Machu Picchu itself was a little busy, but everything we saw along the way was what made it such a magical experience. I suppose you could say the the journey was the destination.
Thank you Green Machine!
