yes then go to stalteport and show the guy your ticket and he will take you to an island where you catch a legendary pokemon. (i forget which one it is) Comment - I searched for " Where do you find Mt. Chimney on Pokemon Emerald? " and it came up with this ? Why ???
In Pokemon Emerald, Team Magma's hideout is on the jagged pass, between Lavaridge town and Mt. Chimney. You can only get to it from Mt. Chimney, unless your have the acro bike. You must also have the Magma Embelem to access it, which is found at Mt. Pyre
