The Walkmill Falls is the location where the first mill was established in 1606 when Randal MacDonnell gave the lease of a mill to Mathew Logan. Several more mills would develop along the river Bush as it dropped in height through the village. These mills collectively led to the modern name of Bushmills coming into being. The original name for the settlement was Portcaman.
The Walkmill Falls were significant in the development of the world's first public hydro electric tramway, it was here that Anthony and William Traill built their power station and installed water turbines the electricity which would power the tram from Portrush to Bushmills and later to the Giants Causeway. The old generating station building is still standing.
It is a beautiful location which once had a path along the river bank from the village, there was even a walkway crossing the river below Heronshaw. If you want to visit the Falls, take the Coleraine road out of Bushmills, about 1km up the road on the left hand side you will see a Presbyterian Church with a beautiful, almost Byzantine designed front doorway, take the next lane to the left.
It is a concrete road which leads to a farm, follow it until it bears to the right, you will see a gate in front of you. Proceeding through this gate will take you to a small car park above the Walkmill Falls (Close the gate behind you). It is well worth a visit, especially when the Salmon are running and a good flow of water is on the river. The area is well used by fishermen and there is an area which allows access and use for fishermen with disabilities.
