When people talk about Los Tanques Azules being "out there," it's no exaggeration on their part. To get a sense of how just how remote the site is, you'll have to travel an hour on foot (3 km to the tiny village of Caletones) and another 40 minutes by car (20 km) just to reach the nearest town of any significant size, Gibara (population approx. 75,000), which is itself touted as being one of the country's best kept secrets. That said, if you happen to be making your way along the Atlantic coast of eastern Cuba, and fancy a swim or a dive in the nearly unexplored, crystal clear waters of one of planet Earth's largest underwater cave systems, have we got an adventure for you.
Like Mexico, Cuba is home to its fair share of cenotes, or flooded caverns whose limestone roofs have collapsed. What makes Los Tanques Azules (The Blue Tanks) so impressive is not only the size of the interconnected caves, but their age (approx. 20 million years), distinctive rock formations, and unique marine life as well. Should you decide to book a dive (which is not a piece of cake, but we've included links), rest assured that the cave has been marked out and lined ahead of time. The descent is made through a small, somewhat unaccommodating-looking opening into what's been dubbed "The Green Hole." From there, a clear, remote, cavernous aquatic world comes to life, complete with giant stalactites, stalagmites and the occasional blind fish sighting. It's safe to say that this is an unforgettable diving experience.
If you'd prefer to stay on the surface, the trek to Los Tanques Azules is still a rewarding experience, with its main 30m x 15m sinkhole filled with plenty of refreshing, clear water to enjoy. As long as you're careful where you do it, there's also some excellent cliff jumping to be had. Check our links for more details (you'll certainly need them), then make the most of this one-of-a-kind Cuban adventure.
