神秘的溶洞，在灯光的辉映下，五彩斑斓、奇幻迷离。放眼望去，玲珑剔透的钟乳石如奔驰的骏马、屹立的宝塔、倒泄的瀑布，栩栩如生，千姿百态。东兰国家地质公园内溶洞众多，列宁岩、兰木地宫、新烟溶洞、板岜溶洞等都是典型代表。

With the lamplight shining, the magic karst cave looks colorful and fantastic. Looking around, the exquisite stalactites are of various shapes, among which, some looks like chasing horses, others shaped like towering pagoda and fallen waterfall. What a vivid scenery with vitality! There are lots of karst caves in Donglan National Geopark, most of the representatives are Lenin rock, Lanmu underground palace, Xinyan cave, Banyi cave. etc.
