Eterna Forest in Pokémon Platinum
Eterna Forest

Eterna Forest is the dark, maze-like woods that Route 205 passes through on the way from Floaroma Town to Eterna City. When you first enter, a Trainer named Cheryl asks you to escort her through, healing your team and fighting alongside you in double battles. A side path cleared with Cut leads to the haunted Old Chateau, and the forest's Moss Rock lets Eevee evolve into Leafeon.
