The Buller Gorge is one of New Zealand's scenic wonders that should be added to your "must see" list. A remarkable landmark located in the Lower Buller Gorge is Hawks Crag. It's a narrow piece of road carved out of an overhanging rock face. With the mighty Buller River thundering below it. The cliff at Hawks Crag is almost vertical, which certainly created a challenge when constructing a road through it in 1869. The solution was to cut a narrow slot across the cliff face. It was a painstaking task.
