Dive-site story
Located along the Barra Strait connecting the northern and southern basins of the Bras d'Or Lake inland sea, Grand Narrows offers a mix of bridge structure, rocky channel slopes, and historical remnants. Water flow through this constriction sustains a dense population of benthic invertebrates and bottom-dwelling fish, though timing the dive around tidal slack is essential.
Bridge structure supports encrusting organisms and congregating fish schools
Rocky bottom littered with natural crevices that shelter large lobsters and crabs
Drift opportunities along the channel edges during gentle tidal transitions
