The Smurf Forest is the current and general location of the Smurf Village where the Smurfs live, seen in all modern interpretations of the Smurfs stories. It is a flourishing animal-filled forest that is home to various species of animals and other mythical beings, not to mention the home of the evil human wizard Gargamel. Its exact location is unknown, though in the 2011 Smurfs movie it is suggested that it was in Belgium due to Peyo (their creator in the real world) having documented their existence as a local historical legend similar to leprechauns.
In the comic books, the Comte d'Aubenas owns property in the Smurf Forest and has attempted to clear-cut the forest so that he could build a gaming complex.
Prior to the Smurfs starring in their own comic book series, the Smurf Village was originally located in a desolate rock-filled forest called the Cursed Land, which was first seen in the original comic book version of "The Smurfs And The Magic Flute". It is most likely that the relocation of the Smurf Village to the Smurf Forest is the result of a retcon.
