蓬萊島

蓬萊島名稱由來是因為其正面有一處與台灣島形狀頗為相似的大岩塊。從終極岩通往集合場的小徑，仔細看看右邊會有一條小路，轉進去20公尺就可以看到隱藏在樹林後面的蓬萊島，此區有很大的懸岩地形，也有一面看似垂直，但實際上是一個將近15˚懸岩的Face。大多數都是指力型態的路線。蓬萊島兩側懸岩直上也都是有開發潛力的路線，單步難度估計都在V8以上。
“Taiwan Boulder” is named by a Taiwan shape rock in front of the boulder. You can get here from the trail to “Assembling Field.” Take a look on your right, and you will find the entrance to ‘Taiwan Boulder.” There are two faces can be climbed, one has a big overhang and another is a 15˚ tilt face. The boulder’s height is only about 9 meters, so the routes here are almost pure power style.
