Iona - Grand Narrows - Nova Scotia
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.
