As on Animal Mountain, this one of the two known entrances to complex cave. It is located about one fourth up the volcano, and can be accessed by rock climbing or tree climbing, whichever the traveler prefers. It is a small ledge out of the mountain with a cave entrance on it. Here you can enter complex cave, a deep dark maze of tunnels. The rock in these tunnels have some glittery stuff in them. It is a deep maze that can lead you in between the islands or somewhere completely else. It is very easy to get lost.
