The highest pass over the Southern Alps, Arthur's Pass was historically known to Maori hunting parties as a route between east and west. The eastern side of Arthur's Pass National Park is characterised by wide, shingle-filled riverbeds and vast beech forests. The western side of the park, where wet weather is more common than dry, has deeply gorged rivers flowing through dense rainforest. Down the middle of 'the great divide' is an alpine dreamland of snow-covered peaks, glaciers and scree slopes. Most people arrive in Arthur's Pass National Park by road - a spectacular piece of extreme civil engineering involving viaducts, bridges, rock shelters and waterfalls redirected into chutes. When Arthur Dobson first encountered the precipitous Otira Gorge, the pass was almost impassable - he had to leave his horse at the top and lower his dog on a rope. Another way to experience Arthur's Pass is on the TranzAlpine Train from Christchurch. After your scenic train journey you can spend the day exploring Arthur's Park National Park, walk through New Zealand native forest, enjoy lunch at a cosy cafe, and look for cheeky kea. A return train departs Arthur's Pass at 4pm and arrives back in Christchurch at 6pm. The park includes many peaks over 2000 metres - the highest is Mount Murchison at 2,400 metres. All the main valleys of the park are deep and steep sided, with the U-shaped profile typical of glacial action. Above the sub-alpine shrublands, there are enchanting alpine fields with wild flowers. The village at Arthur's Pass is the starting point for many short walks. The entrance to the historic Otira rail tunnel can be seen here - an epic engineering feat through 8.5 kilometres of rock. Before you embark on a walk, let someone responsible know where you are going, and when you intend to return. Make sure you let them know when you return!
