In April 2016 the 2 mountains of Machu Picchu will be closed to visitors while important maintenance work is done, the high amount of traffic on these paths making the work impossible under normal circumstances. Machu Picchu and Huayna Picchu mountains tower over the main site of Machu Picchu on either side and provide a different perspective for travelers, as such they are very popular. Travelers should either book their tickets for the mountains well in advance or consider revising their plans to visit Machu Picchu at a different time.General entry tickets will not be affected so only travelers wishing to climb the mountains need to take note of the closures. It is also important to note that the mountains will not be closed at the same time to minimize the disruption caused. Huayna Picchu will be closed from 1-15 April 2016, and Machu Picchu mountain will be closed from 16-30 April. However the closure of one path will obviously put extra strain on the other. Huayna Picchu is limited to 400 tickets per day (split into 7-8am and 10-11am ascents) and Machu Picchu Peak to 800 tickets (7-11am ascent). Alternative treks within Machu Picchu include the 1 hour trek to the sun gate, also giving aerial views over the site or the easier path leading to the Inca Bridge both are easier hikes than climbing the mountains but are impressive nonetheless.
