Circuit 2 remains the only route at Machu Picchu that grants access to all three terrace levels, the Sacred Plaza, and the Intihuatana stone in a single pass.
When Hiram Bingham mapped the site in 1911, he followed what would later become this circuit's trajectory — ascending through agricultural zones, crossing the urban sector, and pausing at ceremonial platforms that track the solstice sun. The route was formalized in 2022 as part of Peru's capacity-management protocols, yet it preserves the original visitor experience: a gradual climb from the lower terraces through carved stone channels to the high ceremonial core.
The path begins at the agricultural terraces below the Guardian's House, where Inca engineers cut 700 steps into bedrock to create a gravity-fed irrigation system still visible in the stonework. You ascend past storehouses with trapezoidal niches, then enter the urban sector through the main gate. The Sacred Plaza opens to your right — a three-sided courtyard flanked by the Temple of the Three Windows, whose apertures frame Huayna Picchu and the Urubamba gorge 400 meters below. The Principal Temple stands opposite, its massive granite blocks fitted without mortar, each corner aligned to cardinal points.
Circuit 2 is the only route that includes the Intihuatana, a carved granite pillar that served as a ritual solar clock. Bingham called it the "hitching post of the sun," though its Quechua name translates more precisely as "where the sun is tied." The stone sits at 2,430 meters elevation, exposed to equinox and solstice alignments that Inca astronomers used to calibrate the agricultural calendar. From this point, the circuit descends through the Royal Tomb and the Temple of the Condor before exiting near the lower terraces.
Guided day trips from Cusco typically depart before dawn to reach the Historic Sanctuary of Machu Picchu by 06:00, when morning mist still clings to the valley. The journey follows the Urubamba River through Ollantaytambo, then boards the rail line to Aguas Calientes. Most tours include round-trip bus transfers from the train station to the citadel entrance, a 25-minute switchback climb that gains 400 vertical meters. Circuit 2 tours allocate two to three hours inside the archaeological zone, sufficient time to complete the 2.5-kilometer route at a measured pace and photograph the site from the upper terraces without the midday crowds that arrive after 10:00.
