Arviat Shoreline, known locally as Tikirajualaaq, offers a shore-entry snorkelling experience near the Whale's Tail monument. This site is suited for intermediate snorkellers due to challenging conditions, including cold water temperatures, low visibility caused by silt, and the presence of surf and rip currents. Depths are shallow, ranging from 1 to 5 metres with an average of 3 metres. Water temperatures remain very cold throughout the year, peaking at approximately 7°C in late summer and dropping to -2°C during winter months. Given the environmental hazards and extreme temperatures, this site requires careful planning and appropriate thermal protection for all water activities.

Arvia'juaq is a marine reef site located 8 kilometres offshore from Arviat, Canada. This National Historic Site features a unique glacial esker formation that creates natural channels within the reef topography. Diving here is restricted to advanced divers due to the challenging environment, which includes strong currents and extreme water temperatures ranging from -2C to 7C. Access is exclusively by boat. Visibility at the site is variable, fluctuating between 5 and 50 metres depending on conditions. The site is also suitable for snorkelling, offering a 4/5 rating for those prepared for the cold water conditions.
