The Infernal Ledges are an Unexplored Territory in Xenoblade Chronicles X. It is a series of four caves located north of Drongo Caravan in Cauldros. The entrance can be found by descending a sloped path down to the lava level where Calore, the Lava Walker stands. The caves themselves can be difficult to navigate as the only ground is distinct platforms; they must be jumped between carefully. As with all Unexplored Territories, its discovery yields an achievement ("Finding the Infernal Ledges").
