Imagine an underwater world, deep, cool, and inviting. Sunlight penetrates the crystal-clear water, beaming downwards to unknown depths. Blue Hole Spring, also known as Jug Spring by the cave diving community, is the only first magnitude spring located within the park, and is one of many springs that feed the magnificent Ichetucknee River. On average, 67 million gallons of water per day flow from Blue Hole, a fact that is evident when feeling the water push you back as you swim towards the boil.
With water that remains a constant 72 degrees Fahrenheit year-round, this spring can be an all-season experience. Submerge into the deep cyan waters to find another world, shared with many species of turtles and fish. Be sure to bring a mask and fins to fully view the underwater scene when you do.
Swimmers can even catch a glimpse of the cave system that starts 40 feet below the surface. This complex cave system has been measured at nearly 600 feet of twisting passages, some large and cavernous, others with barely enough room to turn around. Remember that this spring is shared with divers- so don’t be surprised when you see someone emerging from the crevices below! If you are cave/cavern SCUBA certified, you can don your gear and take the dive all the way down, keeping in mind that diving is not permitted in the other springs or the river.
Whether you experience this fantastic spring at the surface, or far below it, Blue Hole is an experience not easily forgotten.
