Otterspool Promenade is a riverside walk and accompanying area of parkland in the Aigburth and Grassendale districts of Liverpool, Merseyside, England. The promenade runs along the bank of the River Mersey from just north of Garston docks to Otterspool Park. A narrower footpath and cycleway continues along the riverbank to the city centre, ending at the Albert Dock. The promenade adjoins the former private parkland estates of Cressington Park, Fulwood Park and Grassendale Park. It is notable for the excellent views it gives of shipping in the Mersey and over the river to the Wirral.
Opened in 1950, it was built by landscaping a site that had been used for disposal of household waste, and rubble from the Queensway Tunnel. The stated desire of the local authorities was to 'Firstly...provide a place where the citizens of Liverpool can enjoy their leisure in pleasant surroundings on the banks of the Mersey Estuary. Secondly...for providing a large area where the essential need to the community for the disposal of its refuse could be met economically and by the use of hygienic and up-to-date methods.' ('The opening of the Otterspool Riverside Promenade', J&C Moores Ltd., 1950) In 2006–07 renovations of the promenade were undertaken, including the creation of a sizeable children's playground. The renovations were opened in 2007 with a plaque commemorating the City of Liverpool's 800th anniversary.
