Where Is Grand Cayman in AC Black Flag Resynced?

Grand Cayman is a small island settlement in the Cruz region, sitting at coordinates (361, 300) on the world map. It’s on the westernmost edge of the region, northwest of Kingston. If you haven’t visited it yet, it will show up as a question mark until you dock the Jackdaw at its pier.
Sail there from Kingston or fast travel if you already have the viewpoint synced. It’s a small settlement with a tavern, a viewpoint tower, and a few collectibles to find — but the secret chest is the main event.
The Grand Cayman Chest: Why You Can’t Reach It Normally
When you arrive at Grand Cayman and explore the western side of the settlement, you’ll spot a blue chest sitting on a narrow rock ledge. It looks easy enough to reach, but there are no handholds, no climbing surfaces, and no parkour angle that gets Edward up there. The cliff face is smooth. Jumping at it does nothing.
Near the base of the viewpoint tower, you’ll overhear a couple having a loud argument. The wife is furious at her husband, who is standing up on that exact ledge. She wants to know how he got up there. The man has no idea — all he remembers is drinking five cups of rum at the tavern.
When Edward walks past and hears this, he mutters: “I’d like to try what he’s drinking.” That single line is the only hint the game gives you. It’s not marked on any map. There’s no quest indicator. The puzzle is entirely social — pay attention to the world around you, and the solution reveals itself.
How to Get the Grand Cayman Secret Chest: Step by Step

Step 1 — Head to the Grand Cayman Tavern
The tavern is in the center of the Grand Cayman settlement, a short walk from the viewpoint tower. It’s marked on your map once you’ve docked at the island’s pier. Head inside and approach the bar counter.
Step 2 — Deal with the Bar Fight (If It Triggers)
When you first interact with the bartender or approach the counter, a brief brawl may trigger with a couple of rowdy locals. This is not optional — you need to finish the fight before the drink-purchase option becomes available. Take them down quickly and the tavern will settle down. After the fight, the bottle on the bar becomes interactable.
Step 3 — Buy Five Drinks
Interact with the bottle on the right side of the bar counter. Each drink costs 25 Reales. Buy one at a time and watch Edward’s vision blur a little more with each cup. You need to buy and drink exactly five — do not leave the tavern between drinks.
The full cost is 125 Reales total, which is very affordable at most stages of the game. If you’re low on Reales, check our resource farming guide to top up your funds first.
Step 4 — Wait for the Blackout
After the fifth drink, the screen fades to black. Edward has passed out. A short transition plays and he wakes up on the ground, buried under a pile of palm leaves — on the exact same ledge where the drunkard was standing. The chest is right beside him.
If the blackout doesn’t trigger after five drinks, buy one or two more. Some players have reported needing a sixth in rare cases. Keep buying until the screen goes fully dark.

Step 5 — Open the Chest
Stand up from the haystack and interact with the blue chest next to you. Kick it open and claim the reward. A Secrets notification with a checkmark will appear on the right side of the screen, confirming the Grand Cayman Secret has been collected.
Grand Cayman Chest Reward: What’s Inside?
The chest contains the Yoke-Form Vessel, an art piece collectible. It’s a decorative item that gets added to Edward’s collection at his Great Inagua manor.
It is not a weapon, outfit, or ship upgrade. On the surface it seems underwhelming — but it’s actually essential for completionists. The Yoke-Form Vessel is one of the art pieces required for the Dilettante trophy or achievement, which asks you to collect all art pieces and fill out the manor. If you’re going for a full trophy run, you cannot skip this chest.
Opening the chest and completing the drinking puzzle also unlocks the Hungover bronze trophy or achievement on the spot, when Edward wakes up in the palm leaves. It’s one of the easiest trophies in the game and a two-for-one reward for this visit.

All Grand Cayman Chests and Secrets
Grand Cayman has three chests and collectibles worth grabbing while you’re on the island. Here’s the full breakdown so you can clear the area in one visit:
Secret Chest at (357, 298) — Yoke-Form Vessel
This is the one described in this guide. Sit on the western side of the settlement near the viewpoint tower, on a clifftop ledge. Reached only by drinking five cups of rum at the tavern and blacking out. Rewards the Yoke-Form Vessel art piece and the Hungover trophy.
Cave Chest at (358, 295) — Reales and Valuables
Located on the southwestern side of Grand Cayman near a cave pool with a Mayan statue. Wade into the water, dive down when you reach the steps, and swim through a small submerged doorway at the bottom. Follow the steps back up to the surface inside the cave and the chest is right there. The reward is a few hundred Reales in assorted valuables — not spectacular, but worth grabbing while you’re on the island.
Soldier Camp Chest at (365, 303) — Reales and Valuables
On the northeastern side of Grand Cayman inside a Spanish soldier encampment. The chest is visible from a distance. The only obstacle is the soldiers guarding it — assassinate them quietly or fight your way through, then loot the chest. Same reward level as the cave chest: several hundred Reales in valuables.
Tips for Clearing Grand Cayman Efficiently
- Sync the viewpoint first. This reveals all collectibles on the island map including the song sheet, data file, and contract markers. Do this before doing anything else on Grand Cayman.
- Do the tavern chest last. Clear the other two chests and any contracts first, then head to the tavern. After you black out and wake up, you’ll be in a slightly different part of the island and will need to walk back to dock anyway.
- Don’t leave the tavern mid-drink. Buy all five drinks in one session. The intoxication state is not saved if you leave and return.
- Bring enough Reales. 125 Reales for the drinks is cheap, but make sure you have at least that on hand before you head in.
- Listen to world dialogue. The drunk man at the viewpoint is the game’s only clue. This is one of several moments in Black Flag Resynced where environmental storytelling points you toward a hidden secret. It’s worth slowing down and listening to NPC conversations as you explore.
Speaking of hidden tricks, our AC Black Flag Resynced Anomalies guide covers another new system that many players are missing — those glowing white icons on your map are worth your time and unlock free gear through the Animus Projects system.
Is the Grand Cayman Chest Missable?
No. Nothing in AC Black Flag Resynced is permanently missable. The island and its chest stay accessible throughout the entire game, including after the credits roll. You can go back and complete it at any point in free roam.
That said, if you’re aiming for the Dilettante trophy or 100% completion, it’s smart to clear Grand Cayman during your natural exploration of the Cruz region rather than leaving it for a post-game cleanup run. Our full missions guide and the post-story checklist can help you stay organized across the whole map.
You can pick up AC Black Flag Resynced on PlayStation Store, Xbox, Steam, and Epic Games Store.
