I'm heading over to Peru in early September to trek the Inca Trail, I have been told that it can become very cold in the evening and was therefore wondering if anyone can suggest the type or class of sleeping bag i should take with me? I would also be grateful to hear any suggestions of other things that I should take and any hints or tips.
I just completed the Inca trail in mid June. At this time of the year it was really cold at night (well below 0 degrees Celsius) on the first and second nights due to the altitudes you sleep at. I needed a very warm jacket and thermal underwear for the evenings. I'm not 100% sure what it will be like in September but it will probably be cold at night.
I would recommend speaking or emailing the company you are doing the trek with for advice about the temperature at that time of the year. They are usually very helpful with any questions you may have about the trek.
We just rented sleeping bags through our trekking company and they were warm enough. Maybe you can consider that if you haven't got a suitable one.
I would recommend hiring a porter for the trek as well. It is one of the best decisions I made as it allowed me to enjoy the trek much more then others in our group who really struggled every day to carry all their own gear.
The Inca Trail is such an amazing experience, you are sure to have an amazing time!
