Grand Colombier
The bird rock - the seabird islet off Saint-Pierre where puffins and storm-petrels colonise the cliffs each summer.

Off Saint-Pierre's northern point, Grand Colombier serves as the archipelago's seabird capital: the steep islet hosts summer colonies at North Atlantic scale - Atlantic puffins whirring between burrows, razorbills and murres on the ledges, and one of the region's notable Leach's storm-petrel populations arriving after dark - all viewed from tour boats that circle beneath the cliffs without landing, the colonies' racket and fish-run traffic constituting the show. Whales and dolphins frequently audit the crossings, and the islet's green cap against grey cliff and fog makes the classic photograph.
What you actually see
- The puffin traffic - whirring commuters at burrow height.
- The ledge colonies - razorbills and murres stacked on rock.
- The circling view - cliffs and racket from the zodiac.
- The channel cetaceans - whales auditing the crossing.
When to go
June to August is colony season; calm mornings ride best - fog is a native passenger and reschedules honestly.
Honest expectations
No landings - the islet belongs to the birds; zodiac swell and spray reward waterproofs. Fog cancellations are the archipelago's standing terms.
Nearby
Saint-Pierre's harbour and Ile aux Marins.
