The Kepler Mire, also known as the String Bog, is a fascinating wetland located in New Zealand. The mire is home to a variety of plant species, including sedges and mosses, which thrive in the damp conditions. Also, it's one of the LOTR locations.

(Gollum guides Frodo and Sam through the swamp, saving Frodo as he falls under spell of the dead that seem to float within it. )
