秋芳洞(秋芳洞)是日本最大的石灰岩洞窟系统,已探勘的通道达10.7公里,其中1公里沿地下河、以铺面照明步道开放。此洞历经3亿年由雨水溶蚀上方的喀斯特石灰岩台地(秋吉台)而成,形成高达35公尺、如教堂般的空间,倾泻的流石地形,以及以琥珀色光照亮、高15公尺的巨大石笋「黄金柱」。
穿越秋芳洞的主路线沿秋芳川而行,河水全年恒温17℃,使洞内夏凉冬暖。地质构造包含边石池(棚田,如梯田般的矿物水池)、如冻结瀑布般垂悬的钟乳石,以及状似层叠餐盘的石灰岩板「百枚皿」。洞的规模令人震撼:入口厅室(青天井)长175公尺、宽80公尺、高35公尺。数世纪前即见于当地传说,1920年代经科学勘查,1926年开放观光。
