Terdrom, also known as Zhoto Tidro, is a Drigung Kagyu cave site and hermitage located near Drigung Til in the Medro Gungkar county in U, famous for its hot springs and active nunnery. According to legend Tri Songdetsen, Yeshe Tsogyel, and Padmasambhava once took refuge there from hostile Bonpo priests, during which time Padmasambhava concealed treasure. Although a Kadampa hermitage was likely the first edifice there, and Dorje Lingpa is said to have revelealed treasure there, it was developed as a formal meditation site in the sixteenth century by Rinchen Puntsok Chokyi Gyelpo, the seventeenth abbot of Drigung Til.
