We had heard from a few people that the last day of the Heaphy Great Walk (when walking east to west) was highly recommended. We thought it would be a great warmup backpacking trip for us, and it eliminated any transportation issues (ie how to get back to our car if we did the entire tramp). It is a one day (15km) walk from the Kohaihai campground to the Heaphy Hut, walking north along the west coast through semi-tropical bush and alongside the beach, with the Tasman Sea crashing against the shore. Wow.
