The main road between Christchurch and Greymouth on the west coast of New Zealand's South Island attracts many tourists to this tour. The snowy mountains, the flowing waterfalls, the clear lakes, the magnificent glaciers, especially the diversified mountaineering trails and meticulous travel services, have been favored by many mountaineers. For most tourists traveling around the South Island, if Christchurch is the starting point, you can take Arthur Pass as the first stop and appetizer; if Christchurch is the end point, you must have been visually tired to see Arthur Pass.
