The Inca trail is in the Andes mountain range and passes through several cloud forest and alpine tundra. The trail will help you discover various settlements, tunnels, and many Incan ruins. This will be one of your most remarkable journeys. Many trekkers opt for four or five days to complete the "Classic Inca Trail" to discover the paths fully. The Peruvian government has placed a limit on the number of hikers on this trail per season and guides after concerns of erosion were raised.
