Russell Cave National Monument is a U.S. National Monument in northeastern Alabama, close to the town of Bridgeport. The monument was established in 1961 to preserve a shelter which was used for thousands of years as a shelter by cultures of prehistoric Indians for over 9,000 years. It is one of the earliest-known human settlement in the southeastern US. The Cave is believed to have primarily served as a seasonal winter shelter. With a mapped length of 7.2 miles, Russell Cave is the third-longest mapped cave in Alabama. It is 90th on the US Long Cave List. While Caving is no longer allowed inside the cave, guided tours of the shelter area are available. Russell Cave is participating in the NPS Bark Ranger program if you bring canine companions along.
The site also offer trails for hiking, but there are signs about venomous snakes. The area is on the North Alabama Birding Trail.
