Diving Spots that are as beautiful as they are deadly

Jacob's Well
In Wimberly, Texas, there lies a well... but not just any type of well. This well, specifically, is underwater and goes down a depth of at least 100 feet, leading to a dark, dismal abyss that not many divers are keen on discovering. The depths below are disorienting, to say the least, but it's also a very narrow passageway which leads to the risk of being caught on the sides of the well itself.
Cenote Esqueleto
The danger surrounding Cenote Esqueleto, also known as the 'Temple of Doom' in Mexico, is actually the lack of light. While its underwater features are not as perilous as those of underground caverns, there are certain places at the dive site where little to no light breaches the water, making it nearly impossible to figure out where you've come from or where you're going.
Blue Hole
The Blue Hole in Belize has attracted more people from all over the world than any other, simply due to its unique nature. The hole itself seems to just disappear and drop into a dark abyss, with the markings of its depth able to be seen from an aerial view.
Devil's Cave System
The alluring clearness and warmth of Florida's Ginnie Springs are two things that attract divers to this site in the first place, but those who are inexperienced find out very quickly that it's rough edges and steep turns can dislodge equipment or even destroy it, leading to serious problems if they've made it too far into the cave system.
Eagle's Nest Sinkhole
Florida's Eagle's Nest Sinkhole has come with several warnings and is often referred to as the 'Mount Everest of diving.' The narrow tunnels take an unbelievable amount of skill to navigate and divers have no choice - they must remain calm in every situation, unless they're looking to use up their air supply before even making it to the largest underwater cavern, appropriately named the 'Grand Ballroom.'
Samaesan Hole
Samaesan Hole is the most dangerous dive site in Thailand and for more reasons than one. The hole itself descends 280 straight down and along the way, divers need to be wary of unexploded artillery that may have been left over from another era. The site was once a dumping ground for the military, therefore divers need to be especially cautious when exploring its depths.
