is a low point (approximately 1,600 feet above sea level) in the Cumberland Mountains where the states of Kentucky, Tennessee and Virginia meet. The gap was formed by an ancient creek, flowing southward, which cut through the land being pushed up to form the mountains. As the land rose, the creek eventually reversed direction and flowed into the Cumberland River to the north, leaving a natural 12-mile-long path through the mountains.

It was named for Prince William Augustus, Duke of Cumberland, who had many places named for him in the American colonies after the Battle of Culloden. American explorer Dr. Thomas Walker gave the name to the Cumberland River in 1750, and the name soon spread to many other features in the region, including the Cumberland Gap.

"History" of the Gap

Native Americans had been using the gap for centuries before Europeans settled North America, sometimes as a trade route and sometimes as a "warpath."

In 1775, Daniel Boone, hired by the Transylvania Company, led a company of men to widen the path through the gap to make settlement of Kentucky and Tennessee easier. The Wilderness Road, as the trail came to be known, was widened in the 1790's to accomodate wagon traffic. It is estimated that between 200,000 and 300,000 men, women and children passed through the gap on their way into Kentucky and the Ohio River Valley before 1810.

Through most of the 20th century, US-25, a windy two-lane highway went through the gap. In 1996, the highway was replaced with the four-lane Cumberland Gap Tunnel, which goes under the mountain. The original trail was then restored and is now the "focal point" of Cumberland Gap National Historic Park.
