1. Jacob’s Well, Wimberly, Texas
Part of the danger of this site is that it seems so harmless. You may even see little kids swimming at its surface. It’s a fairly popular swimming hole – and it’s not really dangerous until you don scuba gear and start exploring. As you pass the first and second entryways, you’ll wonder what all the fuss is about. Sure, there are a few tight passageways, but it’s not until you get into the third chamber that things start getting hairy. It’s easy to kick up the gravel here and destroy your visibility. That, combined with the tight space of this passageway can spell disaster for a diver. There’s also a passageway that appears to be an exit, but it is no such thing. Unfortunately, many divers have been confused by this and at least 8 have lost their lives in Jacob’s Well.
2. Temple of Doom, Tulum, Mexico
This is a popular dive site, but don’t let that fool you. It has certainly earned its name. This network of caverns and tight passageways is easy to get lost in, and that can lead to trouble for even the most experienced divers. Diving is a sport on the clock. You simply must be at the surface before you run out of air. It’s very easy to become disoriented and lose your way in Cenote Esqueleto, also known as the Temple of Doom.
3. Samaesan Hole, Samae San Islands, Thailand
When you hear about a dangerous dive site, you probably expect caverns and wrecks. You may even expect strong currents (which this site also has). But you’re probably not too worried about unexploded bombs. Unless you’ve been to Samaesan Hole. This dangerous site gets its reputation from a strong current – it’s not uncommon for divers to unknowingly surface miles from their submersion point – and the fact that this is a former military explosives dumping ground. Oh yes, and let’s not forget the fact that it is deep. A whopping 280 feet, in fact. Indeed, this is a dive for very experienced divers who know how to proceed with caution.
