As you continue moving east from Kalm City toward Oliverβs Farm in Final Fantasy 7 Rebirth Chapter 2, youβll get the chance to discover another Cache Location known as Grassy Viaduct. This Cache Location features three Treasure Chests youβll have to find and open to complete the landmark. Here is how to get them.
Where To Find the Grassy Viaduct Cache Location
The Grassy Viaduct Cache Location is in the Grasslands region, east of Kalm, as you can see on the following map. It is only several steps east of another Cache Location known as Thresher Waterwheel. This area is first explored after Cloud and his team escape from Kalm City.

Where To Find the Three Grassy Viaduct Treasure Chests
As you approach the location on my map above, consider the gameβs verticality and look up to spot a broken viaduct. Unlike other Cache Locations, youβll need to find three Treasure Chests here. None of them is on the ground, meaning youβll need to climb the viaduct.
To find the climbing spot while facing Oliverβs Farm (east on your map), make sure that the broken viaduct is on your left side. Keep an eye on the viaductβs wall to spot several yellow ledges that can help Cloud reach the top of the wall.

Approach the ledges and start climbing them. Then, when you reach the top, head right to find the first Grassy Viaduct Treasure Chest at the edge of the wall. Inside, youβll find three potions. After you open it, retrace your steps and check the other side of the upper wall.
The second chest in Grassy Viaduct is near some stairs and contains an emerald. The third one is several steps away, near a broken wall, and inside it, youβll find three plumes of Phoenix Down.
After you get both Chests, climb down using the same ledges and head to Oliverβs Farm following the story. Once you tame Piko, the first Chocobo, I recommend finding the Jadewind Hill Caches.
