I guess the whole island is a little bit of the beaten path. There is no massive tourism here and you can find some very quiet spots on the island. I don't know if I have this impression because I was there in september (no highseason), but sometimes we felt like we where the only tourists there. This place is great to find some peace and quietness in the bussy and glamereous area of the Cote d'Azur.
Historically the island Saint-Honorat is great and many will emphasis their visit with looking at the ancient buildings of the monastry and the monumental chapels. However, don;t forget to enjoy the island itself. It's rocky coastline, that appears from the meditteranean sea water, as it actually is just a mountains that surfaces from the bottom of the sea. The coast and it's dangers made it possible to create a sanctuary here and keep it for centuries 'til now.
As told in the "must see activities" the islands holds seven chapels or remains of them. Three are nothing less then ruins or even only fundaments of what used to be a chapel. The other four are however still standing, with or without the help of continuous restoration work. Their names:
Chapelle de la Trinite
Chapelle Saint Saveur
Chapelle Saint Caprais
Chapelle Saint Pierre
Many people associate the Cote d'Azur with glitter and glamour. Here - they think - is where the rich people live in large estates or expensive yaughts. Other immediately think with the Cote d'Azur about the specific coastline, where high mountains meet the mediterranean sea. Only historical intrested people will feel a drive to go to Ile Saint-Honorat and that is okay, but ... others should also go and enjoy what this mystical place has to offer. Maybe especially those that only are at the Cote d'Azur to be lazy or chase stars in Cannes. It might awaken them from their empty urges.
