I have been trying to find a tour operator for the classic Inca Trail (4 days/3 nights) to Machu Piccu, but have not had any success finding an open spot for one person with any of the tour operators I have contacted. I've read there are at least 160 tour operators and I was thinking it would be a lot easier if I could just obtain a list of all of them. Thus far I've only been able to find the ones I can Google. From there, I eliminated the ones that were over 700 US dollars; however, I certainly didn't find anywhere near 160 operators. Unfortunately, all the ones I contacted said they were sold out in May and June.
I read that the Inca Trail is protected by restricting the number of treks/permits allowed. Is there a way to find out if there are any availabilities left without having to contact each individual tour operator? Also, does there exist a list of all the tour operators?
