The highway from Arrow Town to Queen Town will pass through the Kavalau River. The melting water of glaciers in the southern Alps has created those green lakes, which flow through the mountains on both sides of the river to form the Kavalu River in the canyon. There are extreme sports events beside the river. The most famous ones are bungee jumping, rafting and high-speed motorboats. They are all very exciting, but they go in winter and are very cold. I dare not try.
