The Gerudo Sanctum stands as one of the most mechanically dense dungeons in the Gerudo Desert region. While navigating its shifting sands and steam-vent puzzles is a challenge in itself, the true mastery of this temple lies in uncovering every hidden cache. Many players find themselves staring at a treasure icon on the map that seems to exist behind a solid wall on the second floor (2F), seemingly impossible to reach from within. This guide breaks down the solution to that specific mystery and every other Gerudo Sanctum chest you need to achieve 100% completion.

The Secret 2F Chest Behind the Wall

Let’s address the most common frustration first: the treasure chest that appears to be trapped behind a wall in the upper levels. If you are standing in the room with the locked doors and the waypoint, looking at your map, you’ll see a chest icon just to the east. However, no amount of pushing, pulling, or "Bind" mechanics will reveal an entrance from this side.

To reach this specific Gerudo Sanctum chest, you must exit the building and head to the roof. On the left side of the rooftop structure, look for a small, isolated patch of sand surrounded by tiles. This isn't just cosmetic; it is a direct portal to the hidden room. You need to use a Hol Mill echo on this sandy tile. The Hol Mill will dig a hole, allowing you to drop straight down into the sealed chamber. Inside, you will find a chest containing 50 Rupees. This is often the final piece of the puzzle for collectors, as it requires thinking outside the dungeon’s internal layout.

Early Dungeon Chests: Small Keys and Rupees

As you first enter the Gerudo Sanctum, the initial rooms set the tone for the mechanical puzzles ahead.

1. The Flying Tile Room (20 Rupees)

From the first waypoint, take the left (west) path. You will enter a room that immediately locks behind you, and floor tiles will begin to fly at you. This is a classic Zelda trap. Instead of running aimlessly, summon a Boulder or a Darknut and stand behind it. Once every tile has shattered against your defense, a chest will materialize in the center of the room. Opening this grants you 20 Rupees.

2. The Rotating Door Puzzle (Small Key)

Returning to the main hub and heading right (east) takes you to a room with conveyor belts and blue gates. Use Bind on the mechanical lever and pull it as far as possible to retract the gate. Once you pass through, you’ll find a door that looks like a vertical bar. Use Bind on this door and walk sideways to rotate it like a revolving door. Behind this hidden rotation is a small room housing a chest with your first Small Key.

Mid-Dungeon Loot: The Golden Egg and Map

After clearing the initial hurdles and heading through the locked northern door, the dungeon opens up into more vertical and sandy challenges.

3. The Sandy Drop (Golden Egg)

In the area filled with rolling Caromadillos, the floor is comprised of thick layers of sand. While you can use ladders to navigate, the most efficient way to find treasure here is by looking for a chest icon buried beneath the sand layers. Using a Hol Mill echo to dig through the central sandy floor will drop you into a secluded nook. Here lies a chest containing a Golden Egg, a rare ingredient for high-tier smoothies.

4. The Poe Room (Dungeon Map)

From the lower waypoint where the stone tablet mentions "two distinct tributes," head west. You will encounter a Poe. After defeating it (which also grants you a valuable echo for late-game combat), open the chest in the back of the room to retrieve the Dungeon Map. This is vital for visualizing the remaining chest locations we are discussing.

5. Sand Mound Clearing (10 Rock Salt)

East of the central tribute room, there is a chamber covered in large mounds of sand. Don't just walk over them. Use a Wind Cannon or a Tornado echo to blow away the sand dunes. One of these mounds conceals a chest containing 10 portions of Rock Salt. While not a high-value item, it's essential for those looking to clear the map icon.

The Exterior Treasures of the Sanctum

The Gerudo Sanctum is unique because several of its "dungeon chests" are actually located on the exterior balconies and towers of the structure.

6. The Buried Sand Chest (20 Rupees)

When you exit to the southern exterior area, follow the path toward the elevated platforms. Near a cluster of enemies, you’ll see a chest partially buried in the sand. A simple use of the Wind Cannon or just interacting with it will yield another 20 Rupees.

7. The Aligned Pillar (50 Rupees)

Continuing your climb outside, you will encounter a large, segmented circular pillar with a ladder that doesn't quite line up. Use Bind on the middle section of the pillar and pull it to the left or right until the ladder rungs align perfectly. Climb to the very top to find a chest with 50 Rupees.

8. The Rooftop Dune (Monster Stone)

On the highest point of the sanctum’s exterior, there are more sand mounds. Similar to the interior puzzle, use a Wind Cannon to clear the sand. One of these spots hides a chest containing a Monster Stone, which is crucial for upgrading your clockwork companions later in the game.

Late-Stage Chests: The Big Key and More

Once you have defeated the "Link" doppelganger and acquired the Bow of Might, you can access the final tier of treasures.

9. The Fire Pillar Room (Small Key)

Beyond the miniboss room, you’ll enter a corridor with flame-spraying turrets. To reach the chest at the end, you must block the flames. Summon a Boulder or use a Cat Statue (acquired in the previous room) to push ahead of you on the conveyor belts. At the far left of this gauntlet is a chest containing the Small Key needed for the final tribute area.

10. The Big Key Puzzle

The most complex chest to unlock is the Big Key. After placing the Hawk Statue (left) and the Elephant Statue (right) on the pedestals in the tribute room, a path opens to a room with a massive sand plug. Pull the plug to drain the room, then enter the lower chamber. You will see a large blue and red circular mechanism. You must use Bind to rotate the outer and inner rings until the gaps align with the chest platform. Once aligned, the path to the Big Key is clear.

Essential Echoes for Treasure Hunting

To ensure you don't miss any Gerudo Sanctum chest, keep these specific echoes in your quick-access menu:

  • Hol Mill: The only way to get the "Behind the Wall" chest and the Golden Egg.
  • Wind Cannon / Tornado: Necessary for any chest buried under sand mounds.
  • Boulder: Vital for blocking steam and floor tiles in the early rooms.
  • Platboom: Excellent for reaching the higher exterior platforms without needing to align every ladder perfectly.
  • Flying Tile: Great for crossing large gaps in the conveyor belt rooms if you haven't mastered the Bind-and-move technique.

Navigating the Gerudo Sanctum requires a blend of spatial awareness and the right tools. By utilizing the exterior roof access and keeping a sharp eye on sandy mounds, you can ensure that no treasure is left behind in the desert. The rewards, particularly the Monster Stone and Golden Egg, provide a significant advantage for the challenges that follow in the Jabul Waters or Hyrule Castle.
