An hour north of Christchurch is a disposal facility called Kate Valley Landfill. The total site is 1000 hectares of which 37 hectares is used for a landfill operation. Around 410 hectares of this land has been set aside for native forest restoration and wetland creation, giving recreational, educational and scientific opportunities. A public walkway has been developed in this area, from the end of Mt Cass Road to the coast at Pegasus Bay. The walkway opened in 2006. It also traverses a working farm, and takes about three hours return.
