Yerpa, also called Brag Yer-pa, Drak Yerpa, Dagyeba, Dayerpa or Trayerpa, is about 16 km northeast of Lhasa on the northern bank of the Kyichu River. Walking for another 10 km, you then reach the spectacular limestone cliffs of the Yerpa Valley, also the location of one group of the famous ancient meditation caves in Tibet. The other famous group of meditation caves in Tibet is located at Chim-puk Hermitage in Lhokha.
In the Valley are a number of small Drak Yerpa temples, shrines and Drak Yerpa hermitages. Also, the cliffs contain meditation sites, some of which are thought to be the earliest known meditation sites in Tibet. There are some of them that can be dated back to pre-Buddhist times. Some more famous are connected with Songtsän Gampo, first emperor to unite Tibet. The Drak Yerpa temple here was founded by Monza Triucham, his Tibetan queen.
