6 Pokémon can be caught at Mistralton Cave in Unova — highlighted on the map below.
Reaching Mistralton Cave requires Surfing from Route 6 in western Unova, though Black 2 and White 2 add a second approach through the western end of Clay Tunnel. Darkness fills the interior, making Flash necessary to light the whole cave. Deep inside lies the Guidance Chamber, where the Legendary Pokémon Cobalion resides in Black and White; in the sequels, Cobalion has relocated to Route 13.
