A dense forest, cool and damp in every season, surrounds the lake, and the branches of its trees are covered with green lichen. Because mist and clouds so often obscure the lake, some have likened it to a shy maiden hiding herself behind a white veil. Hence, its moniker: "the 17-year-old lake."
湖的四周森林密佈，由於常年低溫潮濕，樹枝都鋪上一層綠色地衣，加上終年山嵐繚繞，宛如覆蓋白紗的少女般嬌羞，而有「十七歲之湖」美稱。
