Forbidden Pool

The Forbidden Pool was a basin of water created by the waterfall that concealed one of the two entrances into Henneth Annûn, the hiding place of the Rangers of Ithilien.
== History ==
The Rangers fiercely protected the secrecy of their refuge. Anyone who came to the place unbidden was to be killed, and this pool was deemed one of the boundaries. Gollum, searching for fish, chanced to find the pool by accident, but was spared death thanks to his master, Frodo Baggins.
