The Eterna Forest is a forest located between Floaroma Town and Eterna City, in Sinnoh. It is accessible in Pokémon DPPt.
The player meets Cheryl (Pokemon) (Momi) here, and escorts her to the exit.
Places of interest within the Eterna Forest include:
- The Old Chateau (Pokemon), a haunted abandoned manor.
- A Moss Rock, which allows Eevee to evolve into Leafeon within the forest's boundaries, except the Old Chateau.
