Mount Coronet
From Bulbapedia, the community-driven Pokémon encyclopedia.
The Tengan Mountains are a long range of mountains that divide the Sinnoh region in half. Most of it is a deep cave, though there are several above-ground areas.
At the top is the Spear Pillar, where Dialga or Palkia are awakened, and where the Beginning Dimension is reached.
Trivia
- The Tengan Mountains are the only location in Sinnoh where the elusive Pokémon Feebas can be caught. It only appears in four fishing spots in the basement, which change every day, and must be fished with the Super Rod.
- Magneton and Nosepass can only be evolved into Magnezone and Probopass, respectively, by leveling them up here.
