Included in the park are glaciers, scenic lakes and dense temperate rainforest, as well as remains of old gold mining towns along the coast. Franz Josef Glacier and Fox Glacier are two popular tourist attractions located within Westland Tai Poutini National Park. The park offers hunting opportunities for Red Deer, Chamois and Tahr and helicopter access allows hunters access to the rugged mountain areas. The popular Copland Track runs upstream from the Karangarua River bridge. Along with the mountain scenery visible from the track, there are hot springs at Welcome Flat Hut.
In 2010 over 4,400 ha were added to the park consisting of a number of areas scattered throughout the park with the majority being to the east of Okarito Lagoon.
