The land of West Coast is very scenic, with wild coastlines, mountains and a very high proportion of native bush, much of it native temperate rain forest. It is the only part of New Zealand where significant tracts of lowland forest remain: elsewhere, for instance on the Canterbury Plains and in the Firth of Thames, they have been almost completely destroyed for settlement and agriculture. Scenic areas include the Haast Pass, Fox and Franz Josef Glaciers, Jordale Rocks, the Pancake Rocks at Punakaiki and the Heaphy Track.
The region has a very high rainfall due to the prevailing northwesterly wind pattern and the location of the Southern Alps, which give rise to heavy orographic precipitation. The rain shadow effect is responsible for the relatively arid climate of the Canterbury Plains on the other side of the Southern Alps.
