All Cauldron Locations Horizon Forbidden West Complete Guide

Exploring the post-apocalyptic expanse of Horizon Forbidden West requires players to master advanced combat, survival strategies, and machine overrides. Finding every subterranean forge scattered across the map unlocks the ability to turn deadly mechanical beasts into loyal combat allies or fast mounts. This guide details the essential locations and requirements needed to conquer every facility in Aloy's journey.

Story-Related Core Facilities

Two major facilities are directly integrated into the main campaign of Horizon Forbidden West. Repair Bay TAU, located in Plainsong, introduces players to early machine overrides during a critical story quest. Later in the campaign, Cauldron GEMINI becomes available in the central desert region near Scalding Spear. Completing these story dungeons ensures essential progression and unlocks key traversal options across the continent.

Early to Mid-Game Underground Sites

Optional exploration begins with Cauldron MU, nestled in the southern mountains near Stone's Edge. This location offers beginner-friendly platforming puzzles and unlocks basic overrides like Scrappers and Scroungers. For players expanding their movement capabilities, Cauldron IOTA lies far to the north near Salt Bite. Reaching IOTA requires navigating a hidden cave system, but completing it rewards players by repairing a stuck Tallneck.

Late-Game High Difficulty Challenges

Deep within the southwestern jungle lies Cauldron CHI, positioned near the coast southeast of Thornmarsh. Players must locate a hidden entrance behind a scenic waterfall before tackling its complex puzzle mechanics. Cauldron KAPPA represents the absolute peak of endgame difficulty, located in the far northwestern ocean bay west of The Bulwark. Requiring a diving mask to navigate its submerged chambers, KAPPA grants full control over apex predators like the Thunderjaw and Slitherfang.
