It is in fact a canyon, whose bottom, the luxuriant valley of the River Pekerisan, is reached by a flight of steps. Its banks hide one of Bali's most ancient archaeological treasures: surprising almost 7m-high niches carved into the rock, each housing a funerary temple. Four are located on one bank, five on the other bank, and a tenth is 1km downstream. They are 11C royal tombs: the group of five is dedicated to King Udayana and his family, the other four to the concubines of Anak Wungsu, his brother and successor.
