Borderlands 4 (BL4): Fortress Locations & Interactive Tracking Guide

Borderlands 4 Fortresses are large enemy strongholds located across the planet Kairos. There are three unique Fortresses in the game—one for each major region—and each is densely populated with mobs and culminates in a major Boss encounter.

While you will naturally discover these Fortresses by progressing through the main campaign, they are key locations for testing your build and farming loot.

Note: Be prepared before entering a Fortress. These areas feature high enemy density and require significant firepower to reach the final boss.

Their locations have been clearly marked on our interactive Borderlands 4 regional maps, and you can access them using the links in the following table.
