Haast Pass road was only completed in the 1960s. The terrain is difficult and the number of bridges on this highway  is considerable. The pass itself is steep but relatively short.  It is worth stopping at the Gates of Haast bridge for a photo opportunity.   This trip is good in any weather. If it is clear, the view of the river valleys, glacial slopes and mountain tops are magnificent. If the weather is wet, and it often is!  there are a tremendous number of streams which gush from the mountains and make the trip very interesting !
