在越南的山水洞（Sơn Đoòng Cave，目前世界最大的單體洞穴，參考YouTube上的3D模擬，Oxalis的探險記錄或Ryan Deboodt的洞內航拍）被發現以前，鹿洞（曾）是世界最大的洞穴。其實，專家都以各種標準（長度、寬度、高度、內容積等等）來衡量，誰最大還真的不好說。至2009年，鹿洞已知通道有4.1公里，南邊的洞口設有棧道讓遊客進入，參觀有174米寬、122米高的主洞。鹿洞裡住著幾百萬隻蝙蝠，排泄量以噸為計，所以，洞內充滿著亞摩尼亞的氣味，排泄物融入水裡，引來了巨鹿到此喝鹽水。當然，現今已沒有巨鹿的踪影，只留下了鹿洞為名。徬晚時分，只要天氣不差，都能在鹿洞外欣賞蝙蝠出洞，看那一批批的蝙蝠出洞覓食，就像一條條黑色的彩帶在空中飛舞。
Before discovery of Sơn Đoòng Cave in Vietnam (see YouTube: 3D Modeling, Oxalis Expedition 2017, or Drone video by Ryan Deboodt), Deer Cave was always claimed as the largest cave of the world. There’re still a lot of discussions about which cave is the largest, as there are no standard measurement for the largest cave passage. Until 2009, the known passage of Deer Cave is 4.1 km. The main chamber, which is partially lit by sunlight, is 174 meters wide and 122 meters high. There are millions of bats living in Deer Cave, and, if the weather is good, tourists can enjoy the spectacular view of dancing black belts emerging from the cave to search for food.

鹿洞洞口的這一片曾經是以前洞身，崩塌後洞口往內移，暴露在陽光下的這塊就變成了小林野。

往洞裡走。


從石縫可以看出是崩塌形成的，而且舊的洞身應該有兩層。







主洞的高度不少於120米。
The height of the main cave is not less than 120 meter.

看著這些黑色的彩帶飛舞，很有趣，只是後面那群“啊！啊！”聲狂叫的人很討厭。
It’s very interesting to see these dancing belts passing in sky, only the people who’re shouting behind us were very annoying.
