Oliver Sound is a long, narrow fjord located in Sirmilik National Park on northern Baffin Island, Nunavut, south of the community of Pond Inlet. This coastal saltwater feature is characterized by high cliffs, glaciers, and ice caps that surround its deep waters. The park's remote and rugged nature means there are no formal facilities, launches, or amenities for paddlers; access is typically arranged through guided expeditions or outfitters operating from Pond Inlet or Arctic Bay. The primary paddling season is from July to early September, when the ice has thawed sufficiently for navigation. The sound offers a dramatic paddling environment where sea kayakers can navigate among icebergs and along the steep fjord walls. The area is known for its concentrations of marine wildlife, and paddlers may encounter or hear narwhals, beluga whales, seals, and walrus in the adjacent marine waters. The coastal regions also support significant bird colonies, including thick-billed murres and black-legged kittiwakes. The park encompasses numerous archaeological sites evidencing thousands of years of Inuit use, and the area continues to be used for hunting and fishing by local communities. Paddling here requires significant advance planning, reliance on professional outfitters for safe camps and itineraries, and preparedness for a true High Arctic expedition in an isolated and spectacular landscape.
