Twist Mountain

13 Pokémon can be caught at Twist Mountain in Unova — highlighted on the map below.

Owned by Gym Leader Clay, Twist Mountain resembles a working mine, its complex cave network stretching between Route 7 and Icirrus City in Unova. Winter snow fills the mountain, easing travel in places while sealing certain tunnels. The Ice Rock on its lowest floor lets Eevee evolve into Glaceon, and a nearby Worker gives out one random Kanto, Hoenn, or Sinnoh Fossil daily once the National Pokédex is obtained. The Jet Badge is required for entry in Black and White; in the sequels the mountain opens only after the Hall of Fame, when Clay completes a passage leading in from Driftveil City.
