The route provides a safe pedestrian and cycle route with direct access to and from the Inner Harbour, linking with the existing footway, cycle way and transport network through to the city and beyond.

The route is accessible via a bridge crossing Roath Basin lock next to the Norwegian Church, and takes you past the Environment building, the barrage, which includes locks and bridges, sluice gates, and a fish pass and Cardiff Harbour Building.

The landscaped embankment is a public open space where visitors can walk and picnic with excellent views out over the sea and the bay. A children's play area and 'Age of Coal' exhibition mean there is something for everyone.

Barrage Circles is by Felice Varini and uses the Barrage structures and paint to create a collage that results in circles. These circles are not immediately evident and can only be viewed from one location. The art highlights the many parts that are needed to make up the operational structure of the Barrage.
