7 Days in a Backpacker Campervan exploring the South Island. We loved our time exploring the South Island of New Zealand in a Backpacker Campervan. We saw amazing sites including seals, Keas, sunsets, the towns of Hokitika and Queenstown, Milford Sound, and even picked up a hitchhiker from France. Exploring the South Island of New Zealand in a campervan is a great idea and comes recommended. We went through Backpacker campervans.
