The ancient if modest Urgeyling Gompa is where the sixth Dalai Lama was born. Before he left for Lhasa, it's said that he stuck his walking stick into the ground and it eventually grew into a giant oak tree that flanks the entrance to the monastery. Within the main hall are hand-painted portraits of all the Dalai Lamas, and imprints of the forehead and feet of the sixth Dalai Lama.
By road, the gompa is 6km from Tawang town, but much closer if you walk downhill from Tawang Gompa. Note that the monastery is sometimes closed; ask around for the caretaker, who has the only set of keys.
