Yexianggu (Valley of Wild Elephants), covers an area of 369 hectares by the Sancha River in Mengyang Town, and is situated 47 kilometers north of Jinghong City.

The valley, wide open and with hills rolling gently at an altitude ranging from 747 to 1055 meters, is covered by tropical rain forests, crisscrossed by rivers and streams, and teeming with such endangered species as Asian wild elephants, wild oxen, green peacocks and monkeys. Situated at the juncture of the two parts of the Mengyang Nature Reserve, Yexianggu provides a natural thoroughfare for all sorts of animals, and for this reason it is frequented by wild elephants. In fact this is the only place in Xishuangbanna to marvel at the giant animals. With a five-kilometer long passageway, a 300-metre long overhead corridor for elephant-watchers, hotels are built right in the trees, as well as an elephant training school, a butterfly breeding centre, and a caged bird paradise, the Yexianggu Wildlife Valley is a favorite tourist destination in Xishuangbanna.
