Towards the end of the Inca Trail, you'll reach the beautiful, well-restored ruin of Phuyupatamarka (Town Above the Clouds), about 3600m (11,811ft) above sea level, which contains a stunning series of ceremonial baths with water running through them. A ridge here also offers camping - while it's a fabulous spot to watch the sun set, it's also the place where keen trekkers leave at 03:00 in a race to reach the Sun Gate in time for sunrise.
