Another sacred site in the district is the renowned Aja Ney. Pilgrims from all other parts of Bhutan converge here to receive blessings and wash away their sins. A rock that bears 100 renditions of the sacred syllable “Aa,” is said to have been discovered by Guru Padmasambhava. It is located at an altitude of more than 3500m. It is located approximately a two day trek from Serzhong village.
