Billed as being filmed in an "abandoned urban area", this was in fact recorded in the recently-closed Stocznia Gdynia shipyard in the Polish port of Gdynia, one of the busiest container ports on the Baltic and a lively, vibrant city with a population of over a million people. At no time was Grylls more than a few minutes walk from civilization including office buildings, commercial and residential districts and one of the city's main thoroughfares.
