I deffinately recommend the Inca Trail. We did it as part of a G adventures tour. The food was amazing, three courses! The tent and rented sleeping bag and poles were practically brand new.
The guide was lovely and very informative. We did our tour in January and the weather wasn't that bad, a bit of rain but warm as the trek is hard work. I would suggest you do it in three days (we did) as it is a nice pace.
Book well in advance, not bother with expensive trekking boots (I did it in well worn running shoes), a waterproof/wind proof coat is a must! Hire at least one walking pole as the descending is quite steep and you really do need a pole.
The toilets are a bit grim, and there aren't any showers but that's all part of the fun :D !!
Absolutely breathtaking :)
