This has been on my "bucket list" for almost 20 years and I finally organised the time off to do the 4 day 3 night Inca trail trek.
Having just finished the trek I can say it was everything I imagined and more. I booked through Inca Trail Reservations . Xiomara was very helpful with the organisation of the tour, responding the same or next day. I paid extra for a porter and walking stick - well worth it! The sleeping bag I rented was obviously cleaned right before.
The trail was amazing and the guide informative. The only negatives were based on camping - one night was too cold and the ground was always too hard. This wasn't the company's fault as I should have bought or rented a mattress. I would recommend this for the physically fit who want and adventure of a lifetime.
