About Disko Island

Qeqertarsuaq is the practical base for exploring Disko Island's unusual volcanic landscape. Marked routes lead from town toward waterfalls, contorted basalt formations, viewpoints over iceberg-filled Disko Bay, and the high ground near Lyngmark Glacier. June through September is the main window for hiking, sailing, and whale watching, while winter access and activities require a more specialized plan. Reach the island by seasonal boat or helicopter, and allow weather flexibility because a delayed transfer can affect every later connection.
