were thought to be entrances for gods, they believe the Temple's purpose was to be a place of worship to the Gods. There is a theory that it must have been a royal tomb, place of worship and look-out post. Some believe that this was a place for sacrifices, because the structure has beautiful vaulted niches and empty trapezoids of typical Inca type and in front of the cavern, there is a rock sculpted in the shape of an altar. Others think Temple of the Moon was a ceremonial bathing complex. Access The trail that leads from the summit of Huayna Picchu to the Temple and the Great Cave is very exposed and can be quite slippery. A few spots have a steel handrail cable (a via ferrata), but a fall in many places would have severe results. The trail that leads off from the main Huayna Picchu trail near the saddle is easier and safer, but still presents hazards. Expect at least a 45-minute walk in each direction from this lower trail, and at least an hour from the summit down the alternate trail to the ruins, plus the 45-minute walk back uphill and to the main trail.
