The Mackenzie Delta — visible from any high point in town — is a vast flat plain of channels, oxbow lakes, and willow scrub stretching to the horizon. It is one of the most important wildlife habitats in the Arctic: beluga whales calve in the offshore bays in July, caribou herds cross seasonally, and the delta is a critical staging ground for hundreds of thousands of migrating geese and ducks.
Tour operators in Inuvik (Tundra North Tours, Arctic Chalet) run river boat tours from the town dock in summer — half-day or full-day trips through the channels, sometimes including a stop at a Gwich'in fish camp where dryfish is still made the traditional way. In winter the delta is crossed by ice roads.
