When Inca Trail permits have sold out on a given date, the Moonstone Trek can be booked in place of the classic Inca Trail at no extra cost – just request it at the time of booking. The trip must be guaranteed and there is no minimum number of people required to operate the Moonstone trek. However, most people prefer to trek with a group and so we try to avoid running it for just one or two people wherever possible. Special permits are not required and so this route can be booked after Inca Trail permits have run out. Should you opt for the Moonstone Trek on a date where Inca Trail permits are still available, a supplement will apply – please enquire for details.
