The Hinlopen Strait is a passage between the islands of Nordaustlandet and Spitsbergen Island in the Svalbard archipelago. It is often ice-clogged, but it is one of the best spots for wildlife viewing. Walrus, ringed and harp seals, and polar bears may be seen resting on the ice floes. Watch, also, for reindeer, Arctic fox, and bird species such as glaucous gulls and guillemots, which nest on the ice cliffs and basalt pillars along the coastline.
