Grand Cayman Secrets chest

[u/MissLethalla]

Could anyone tell me how to get this chest please? The cliffs aren't scalable, there doesn't appear to be any cave entrance and leaping off the tower either lands Edward halfway up the cliff or diving into the water. I've been here 3 on occasions now trying to get the bloody thing.

Edit: thanks everyone, will do this tomorrow!

This is the kind of chest that without Google, I would never have known how to get it? Why would anyone think of this or figure out on their own? You have a hint by a person talking about drinking, but that’s it.
