After 247 steps, discover the most breathtaking view of Belle-Île. On the ground floor, a permanent exhibition covers various themes: the administration and history of lighthouses, the profession of lighthouse keepers, beaconing, and natural spaces. Visit of the Grand Phare: 20 minutes + self-guided tour of the exhibition (last entry 30 minutes before closing). Limited number of places. No reservation required.
