The place is beautiful and amazing. The water is cold, clear and deep. The area is well maintained and open to the public. The water comes from an underground spring and has the same temperature throughout the year. I went on a cold day in January and saw people floating. Some days you will see people getting certified for scuba. A true oasis with nice, friendly people. Highly recommend.
In fact, it is measured at 125 meters at its deepest point, enough to force divers to carefully plan their descent and ascent to avoid decompression sickness.
The geological process that resulted in the formation of this natural wonder began 153,000 years ago, and ended about 15,000 years ago when this underwater fissure assumed the shape it has today.
A careful analysis of its features reveals that the Great Blue Hole was originally an inland cave, before being flooded by rising sea levels during its history.
The most important reason why people want to see the Great Blue Hole is the biodiversity. In particular, this location is home to several shark species including the Caribbean reef sharks, nurse sharks, hammerheads, bull sharks and black tip sharks.
I'm not sure it is. It is regularly listed on scuba diving discussion boards as very frustrating. Obviously it's a very long ride by boat, and then when you get there it's about 5 minutes of 'this is great!' followed by the rest of the dive 'is that it? No sea life or anything out here?'
I've never been diving myself, but I believe people when they tell me that Belize has a lot of great diving, but the Blue Hole is more of a bucket list item than a truly memorable dive.
Natural Wonder: The Great Blue Hole is a huge underwater sinkhole located off the coast of Belize. As you approach it, you will see a circular formation of deep blue water surrounded by coral reefs. The view from the top is breathtaking, with a dark blue color contrasting with the turquoise waters of the surrounding Caribbean Sea.
Descending into the depths: As you begin your dive, you will descend into the depths of the Great Blue Hole. The crystal-clear water offers excellent visibility, allowing you to see the stalactites and stalagmites that formed when the sinkhole was above sea level during the last ice age. The descent can be a thrilling experience as you explore the depths of this geological wonder.
Marine Life: While the Great Blue Hole isn't known for its abundance of marine life compared to other dive sites in Belize, you can encounter several species of reef sharks, including the Caribbean reef sharks and bull sharks. Additionally, you can come across groupers, barracuda, sea turtles and an array of colorful reef fish. Exploring the rim of the sinkhole allows you to enjoy the diverse marine ecosystem that surrounds it.
Unique Diving Challenges: Diving in the Great Blue Hole presents some unique challenges. The dive usually involves a "free descent" where divers descend without a fixed descent line. Depths can reach about 130 meters (426 ft), making it a dive for experienced divers with proper training and certifications. Factors to consider are nitrogen narcosis and decompression stops during the dive.
Diving Conditions: Diving conditions at the Great Blue Hole are generally calm, with relatively light currents. However, visibility can vary depending on weather conditions and other factors, so choosing the right time for best visibility is essential. Water temperatures are generally warm.
A sense of wonder and adventure: The Great Blue Hole is a UNESCO World Heritage Site and has an air of mystery and wonder. As you explore its depths and witness the geological formations, you can't help but feel a sense of adventure and appreciation for the natural beauty that surrounds you.
