Mt Ember

12 Pokémon can be caught at Mt Ember in Kanto.

A dormant volcano dominating One Island in FireRed and LeafGreen, Mt. Ember takes its name from the glow visible at night, attributed to Moltres, which nests near its peak. A Move Tutor beyond the Ember Spa teaches Explosion, and Rock Smash and Strength open the way through the cave network to the Legendary bird. After the player earns the National Pokédex and speaks with Celio, two Team Rocket Grunts guarding a chasm can be defeated, revealing the Ruby that Celio needs to enable trading with Hoenn.
