I'm guessing that means "longest". In which case it is the Flint Ridge / Mammoth cave system (USA), with a combined total of well over 350 miles of surveyed passages.
The state with the largest cave system in the United States is Kentucky. The Mammoth Cave National Park in Kentucky is home to the world's longest known cave system, with over 400 miles of explored passageways.
Taking "largest" to mean longest... Not easy to establish - different sources quote different lengths but the most extensive is the Flint Ridge - Mammoth Cave system, in Kentucky,with over 350 miles of surveyed passages. Caves over 100 miles long are unusual; one of this magnitude rare.This length is notof a single passage but a complex network.
White Scar Cave was discovered by Christopher Long in 1923.
Saint Benedict stay in the cave for three years

Mammoth Cave has about 390 miles, or about 625 kilometers, of underground passages already mapped, far exceeding any other cave system in the world. And that's just what's been mapped -- spelunkers admit they are nowhere near exploring every last tunnel.
