Everfree Forest

The Everfree Forest is a mysterious place outside Ponyville. Unlike most of Equestria, the forest does not need attention from ponies to function naturally, plants grow and the weather changes without their involvement, and animals care for themselves. This is completely alien for the ponies who feel apprehensive about nature working on its own without intervention. The general pony consensus is, "It's not natural!"

It is home to many strange creatures, including ursas and parasprites and other hazards, such as the plant poison joke. Zecora makes her home in the Everfree Forest, and visits Ponyville every so often.The forest is also the location of the ancient castle where the Elements of Harmony are located.Princess Luna and Princess Celestia once resided there. A comment by Applejack indicates that the forest is not actually part of Equestria. Fluttershy lives in a cottage near the edge of the forest.

When Rainbow Dash panics over her impending performance in Sonic Rainboom, she considers the possibility of being banished into the Everfree Forest for her failure. Twilight Sparkle also considers this in A Bird in the Hoof when she sees the Everfree Forest as the place where she and Fluttershy would be banished (and possibly imprisoned) to for kidnapping Princess Celestia's phoenix, Philomena.
