The Jagged Pass is a steep mountainside path leading down from the summit of the volcano, Mt. Chimney. As its name suggests, the route has steep, sharp ledges and rugged rocks. Some of these rocks can be jumped on when riding the Acro Bike; the bike allows the player to travel up over the ledges which otherwise prevent uphill travel.
In Emerald, the Magma Hideout is located in the middle of the Jagged Pass. If the Key Item Magma Emblem is in the Bag while traveling up or down the mountain face, the doorway to the Hideout will be revealed, allowing the player to enter the cavern. The Magma Emblem is lost by the team at the peak of Mt. Pyre, so the hideout will remain hidden during the player's initial trip down Jagged Pass, although a single Team Magma Grunt can be found in front of the hidden doorway.
In Generation III, the trees that are covered in volcanic ash on the route have numerous shadow issues, with some using two different types of shadows. None of the trees that are not covered in volcanic ash have issues with their shadows.
