Shirley Pump Track is listed at 10 Shirley Road in Richmond, Christchurch. The linked page describes a proposed temporary modular pump track on that site, funded by the city council, with a local push for a permanent track in nearby MacFarlane Park instead. The page is from around 2018 and 2019, so check the current status of the track before planning a visit.
The directory holds no details of the track's layout, hours, access, facilities, or visitor comments beyond the rating, and no figures for other pump tracks or playgrounds nearby. So we can say no more about what it offers or how it compares.
