Simmons Gap is named after Ephraim Seamonds/Simmons who lived at Simmons Gap on the Blue Ridge Mountain. Simmons Gap Road that runs from Buck Mountain Road just north of Earlysville, Virginia to the park line and picks back up on the west side. In the horse and wagon days Simmons Gap was one of the main mountain crossings. Ephriam Seamonds and his wife Mary Pew Seamonds are buried on the mountain. When it was decided to cut a better crossing, the Spotswood Trail was selected which is now Route 33. Simmons Gap sits between Weaver Mountain and Flattop Mountain.
