Appalling service. We booked our Salkantay trek months in advance, using Gulliver’s Expeditions through Bookmundi. Turned up for our pre-departure meeting the evening before the 5 day trek, to find our names were not on the list. Turns out our booking had to be confirmed with the trekking company by 12pm the day before departure, and Bookmundi didn’t confirm till 4pm, so we were unable to go on the trek the next day. Tried to contact someone about it and they were absolutely useless. We were only in Peru for a specific number of days, so we were unable to do the 5 day trek, which was the entire reason we went to Peru in the first place. Ended up cancelling entirely with Bookmundi and booking onto the 4 day trek directly with the trekking company. Can not emphasise enough how awful they were. We were so disappointed not to do the 5 days. You can very easily book in for the trek directly with a trekking company once in Peru, a day or two before you want to start. Avoid these third parties - they charge more and, in our case, completely ruined our experience.
