A list of deep dives will not be complete without the Great Blue Hole. This is a 100-meter wide and 124-meter deep sinkhole formed during the last ice age. 

Below, you’ll see majestic karst limestone formations with ledges that fall into the darkness of its depth. From above, the Great Blue Hole is very visible with its dark waters confirming its deep wonders. The visibility here ranges from 15 to 30 meters.

About 40 meters deep, you can see the stalagmites and stalactites. There are ancient caverns here that add to the mystic appeal of the dive spot. 

Still, don’t let its depth scare you. Below, you’ll see nurse sharks, Caribbean reef sharks, and giant groupers. There are also giant tuna here aside from the pelagic species that you can’t find on shallower waters. 

To reach the Great Blue Hole, you have to ride a boat from San Pedro or Caye Caulker Island. The trip is about two hours away. Even if the hole is very deep, the water is crystal clear. If you’re an experienced diver, a plunge at the Great Blue Hole is an unforgettable experience. 

2. Key Largo, United States

Florida is home to one of the most colorful and diverse dive sites in the United States. This dive spot is 55 meters deep with an amiable water temperature of around 70F. 

The most popular attraction here is the Northern Light. It’s a 300-foot long wreck together with the Spiegel Grove that sits shallower than the latter. The Northern Light freighter is beyond the recreational limits, which is why only a few divers can lay eyes on it.

The catch here is that the current on this dive site can be quite unpredictable. Divers have to follow a special dive technique (hot drop) to reach the wreck and avoid being swept by the strong currents.

 Remember that the Northern Light Wreck is an intermediate dive spot. The good thing here is that the visibility of the wreck ranges from 100 to 150 feet.

On this dive spot, you can see barracudas, nurse sharks, pompano, snappers, and rays. The clear water also makes it very enjoyable to observe marine life during your plunge. 

3. The Pit, Playa del Carmen, Mexico

On the paradise of Playa del Carmen in Mexico, you’ll find The Pit. It’s a cave dive spot that ranges from 36 to 121 meters. This is a complicated cave system with a jump-off that leads to the mainline. If you plan to explore the entire cave, you need to be a full cave diver and use Trimix breathing gas.

In this cenote, divers aim to see the Wakulla room, it’s a massive gut in the save system. If you’re planning to dive on The Pit, don’t expect anything to see within 100 feet. The magic only starts once you reach around 300 feet or 100 meters. 

Many tec divers consider this a milestone dive. The narrow passageways require skill. But if you’re skilled and brave enough, you can feast your eyes on the stalactites on the ceiling of the cenote as well as boulders that are as big as passenger buses.

Another spectacle to witness here is the beams of sunlight streaming through the openings of the cave. It’s an unforgettable experience for every tec diver. 

4. Utila, Honduras

One of the most iconic dive spots in North America is CJ’s Drop Off within the Turtle Harbor Marine Reserve. Here, you can descend to 300 meters. 

For recreational divers, the limit is usually at 130 feet but tec divers can descend the entire depth with proper coordination with the locals. 

At 100 meters and below, your eyes will be treated to big sand craters. Underwater, you can spot barracudas, sea turtles, moray eels, and eagle rays, among others.

During your ascent, you shouldn’t miss watching the reefs below. At Utila, your journey up is as interesting as your descend. The shallow reef plateau is a sight to behold, including its colorful tube sponges and brain corals.

Aside from CJ’s Drop Off, the bay island of Utila is surrounded by dozens of other dive sites. You should also consider The Maze, The Pinnacle, and the Blackish Point. On the other side of the island are dive spots like Little Bight, Big Rock, Utopia Village, and Ted’s Point. 

To go to Utila Island, you need to fly from Roatan or San Pedro Sula.

The Red Sea is probably one of the most popular seas in the world. Aside from the alga that makes its waters turn brownish-red, the Red Sea is also home to many wreck spots. 

The most popular here is SS Thistlegorm which can be reached about three hours away from the Sinai Peninsula. This British transport ship lies 30 meters deep and spans a colossal 128 meters underwater. 

There are regular dive group tours here where they get to see the wreck up close. 

Another highlight of the Red Sea dive is its colorful coral reefs. You should try the Elphinstone Reef, which is reachable from Marsa Alam. This reef is 300 meters long with strong currents often discouraging divers from pursuing its depths. 

Moreover, you can head to the Jackson Reef to witness its coral garden. At 28 meters, you’ll get to spot a rare red anemone. For beginners, there are shallower parts that also offer a visual feast of marine life. 

The Red Sea isn’t the easiest dive spot, but courage is surely worth it.
