France's first protected area under private law, the Sept-Îles ornithological reserve was placed under protection in 1912 by the LPO, which was then fighting against the massacre of Atlantic Puffin on this site. Since then, and its classification as a national nature reserve in 1976, it has attracted many other species. It is home to 25,000 pairs of seabirds, including 175 pairs of Atlantic Puffin (the last colony in mainland France), 157 pairs of Manx Shearwater and 22,000 pairs of Northern Gannet (the only French colony). In addition to the birds, the reserve also hosts a colony of grey seals of about 40 individuals, the second largest in France after the Molène archipelago.



The best way to get close to these birds is to take the passenger boats that offer excursions around this archipelago. (It is also possible to board traditional sailing boats). During this excursion (2-3 hours), you will discover the different islands of the archipelago thanks to the live commentary. Boats leave from the harbour of Trestraou (for info check www.tourisme.perros-guirec.com). Some excursions offer a stopover on Ile aux Moine. Attention: following the bad weather of this winter 2019, the access to the Ile aux Moine is now done by a rope bridge (Monkey Bridge type). It is mobile and therefore unsuitable for people with walking or balance difficulties. Pushchairs and dogs are forbidden.
