Milford Sound

Summer is the most practical season for access and weather in Fiordland.

Milford Sound on New Zealand's South Island is a fjord with a freshwater tannin-stained surface layer that mimics deep-water conditions just below the surface — black coral, basket stars, and species normally found at 100m+ accessible at recreational depth.

What divers say

“Deep-water animals at 15m because the fresh water blocks their light — unlike anywhere else in diving.”
