Mersey Waterfront covers a 135km (84 mile) coastline extending from Southport Marine Lake in the north, where it bounds with the Ribble Estuary Regional Park, to Parkgate on the Wirral Peninsula to the south. The eastern edge is marked by the Trans Pennine Trail where it crosses the Mersey in Warrington.

The River Mersey is the City Region's greatest natural asset, and is home to one of the most famous waterfronts in the world. By bringing together the coastal areas of Halton, Liverpool, Sefton and Wirral (and by using the inland support of Knowsley and St Helens), Mersey Waterfront will improve the unique features of the Liverpool City Region, with the objective of creating an internationally acclaimed waterfront alongside the likes of Toronto and Sydney. Mersey Waterfront has some of the UK’s most stunning and unique coastline environments. Its terrain is rich and challenging, from magnificent beaches, internationally important wildlife habitats and seaside resorts to major ports and industry.

Over 40 regeneration projects have been completed as part of the Mersey Waterfront programme, with collaboration from a range of different organisations.   These interconnected but diverse projects transcend local authority boundaries and range from a purpose-built Cruiseliner facility to new nature reserves, improved access to public realm, business support and community engagement.
