I am planning to travel to Fox Glacier from Greymouth and get back the same evening. Is it too much of stretch to cover that distance in a day ? If not, can some one please suggest what is the best mode of transport ? When I contacted a rental car company, I was told that the depot in Greymouth is small and that there is a minimal rental period for cars . Are there buses in that route ? Intercity buses don't really match the timing I am looking at.
