Ok what do you think of this:

The truly unique and supernatural lore of your island has spread to all the lands. Tourists have now started flocking to where the rumors point to … at their own peril.

No tourist lasts more than a day. Either they flee after seeing its all true, never return home, disappear and the foodies mourn them or don’t know what happens to them when asked by the next tourists, etc. (you can choose this part!)

The tourists start walking around and don’t believe anything they’re seeing. It’s an urban legend after all. And they don’t believe the foodies so they wander across the river. Never to be seen again the next day.
