When you come to Ali, Tibet, in addition to visiting "Mapang Yumtso", one of the three sacred lakes in Tibet, you cannot miss the mysterious lake separated from it by only a hill - Rakshas Lake. It has a scary name, called Ghost Lake, which means "poisonous black lake" in Tibetan (Tibetan: ལག་ངར་མཚོ).
