第3地道(都罗山眺望台) （Dorasan Observatory (The 3rd Tunnel)）据首尔52公里的第3地道发现于1978年10月17日，每小时可通过1万名士兵。北韩在南韩发现第3地道后，马上宣称该地道是南韩为攻打北韩而挖掘的。但地道内部的爆破痕迹皆朝南，北韩捏造的言论也不攻自破。

第3地道旁的都罗山眺望台上不仅能看清楚看到北韩开城市和松岳山景，还能看到北韩农村村民和小孩的活动。

The 3rd Tunnel was discovered on October 17, 1978. It is located 52km from Seoul.
It was estimated that it took approximately an hour for 10,000 soldiers to move through the tunnel.
When this tunnel was first discovered, North Koreans insisted it was made by South Koreans in a plot to invade North Korea. However, this theory proved eventually to be false.
Mt. Dora Observation Platform is located nearby the 3rd Tunnel.
From this observation platform, North Korean military personnel are visible, and so are the highlights of Gaeseong and the Geumgangsan Diamond Mountains.
