Why dive here
With 77+ marine species recorded in the area - including blue sharks, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and jellyfish lake - Iona - Grand Narrows offers some of Nova Scotia's richest diving. Water ranges 1-17°C, warmest August, September, October.
We’re talking about a shore entry into a silty bottom at Grand Narrows, often with visibility settling around 3-5 metres. Look for nudibranchs, small crabs, and the occasional sculpin tucked among the rocks and debris. It's a low-key dive, best for photographers keen on macro subjects or those just looking for a relaxed dip. Don't expect dramatic topography; this is more about the small discoveries.
Safety Notes
Cold water this month (avg 15°C). Drysuit or thick wetsuit (7mm+) recommended.
