Originally a toll point, the canal narrows significantly as it approaches the basin.
Pontymoile Basin was the site of the junction with the three-mile Monmouthshire Canal to Pontnewynydd, containing 11 locks.
[3] The spur was problematic due to water supply issues, and it was overtaken by rail when the Monmouthshire Railway and Canal Company drained it and reused the bed for their railway line in 1854, though it had seen decline prior to that date.
Narrowboats and cruisers can be seen along the private stretch of moorings and day boat hire was introduced in 2007.
The basin is located near Pontypool Park and is a stopping point for boats en route to Goetre Wharf.
