It's a dive site that is seemingly innocuous but has seen at least 130 dive deaths in the past 15 years (incredibly high rate). It's crazy because one free diver went through "The Arch" without any fins. He held his breath for 8 minutes to do so; yet many divers with tanks have died trying to make the same swim. In fact, like Mount Everest, it is a graveyard of bodies who've become landmarks for guiding underwater (like "Green Shoes" on Everest). It's even more odd that the area does not have any dangerous currents.
This video shows a tour of the area. ⚠️ WARNING - Like Everest there are dead explorers in this video who've never been recovered.
