Far Cry 6 has many corners of Yara for Dani and the player to explore. Most of the game will be spent liberating military checkpoints or FND Bases. Far Cry 6 also has plenty of treasures littered in each region that can help build camp facilities or customize weapons.
Occasionally, inspecting notes or talking to NPCs will mark a Treasure Spot on Dani's map. These are easy to follow and marking the quest will quite literally guide the player through each step. However, some treasures are not part of the Treasure Hunt quests and can only be found through exploration. This applies to the chest in San Antonio de Padua Cemetry.
Locating the Crypt Key
First, players want to make sure they're in the right region. San Antonio de Padua Cemetary is in the El Este region. Specifically, it is at Sombreado Gorge, which is in the southern side of Conuco.
The cemetery is mostly abandoned save for one NPC. There are no enemies, so players can check the red door to the crypt without being shot. Inspecting this door will give a pop-up declaring it needs a key. Unfortunately, there aren't any notes that point the player in the direction they need to go. On the other hand, the key isn't too far away.
Start by heading west of the cemetery and look for a white house with a blue shed. This is Freddy's Boneyard and it's where the crypt key is hidden, Make way to the door circled on the above image and break it with Dani's machete.
Inside is a mattress and a chest. Look closely and the key is on the nightstand behind the mattress. Inspect the Handwritten Note on the bed, but this isn't necessary and players can just grab the key and leave. Pick up the resources lying around too.
Finally, backtrack to the cemetery and use the key on the crypt.
The Rewards
Inside are more resources as well as a Supremo-Bond. As one would expect, Supremo-Bonds can be used to modify Supremos.
If Dani read the note in the shed, they can break the wooden boards in the corner of the room. In this section of the crypt, players can find Sofia, the woman mentioned in the Handwritten Note, resting on an altar. Gather up the medicine around her and in the corner of the room.
