Many popular destinations are being stressed by tourist. These issues could become more common as tourism numbers increase.
Milford has become synonymous with beauty, a 54km, four-day tramp through beech forest, over glacier-fed rivers and up the climatic MacKinnon Pass, an alpine crossing more than 1,100 metres above sea-level.
One 100 years ago the Spectator magazine declared Milford “the finest walk in the world” – and the name has stuck.
There are nine “great” walks in New Zealand, with Milford the jewel in the crown. But as its popularity has surged so too have fears from New Zealand trampers and conservationists that the pristine natural environment is being spoilt by the hordes of tourists drawn to its beauty and supposed tranquility.
