Experience the unusual and breathtaking Lake Drummond, a 3,108-acre bowl-shaped lake located near the center of the Great Dismal Swamp. The larger of only two naturally occurring lakes in Virginia, on windless days on the lake, the water appears smooth as glass as the horizon disappears into the sky above. Lake Drummond stands only 18 feet above sea level, and though it is three miles wide, it is only six to seven feet deep, allowing great cypresses to rise from its still, shallow waters. Tannic acid from forest vegetation stains the water.
