10 places to spend the day in the dry in Côtes-d’Armor: museums, aquariums, discovery centres and castles you can visit inside.
A shower in Côtes-d’Armor need not spoil the day if you know where to go. Here are the places in the guide where you stay dry: the sea seen from the inside in aquariums and discovery centres, museums, and castles whose rooms you can visit.
Each place has its own page, with the visit time, access and our tips. Opening hours change with the season and many sites close one day a week outside the school holidays: check them on the venue’s website before you set off.
Breton showers often pass quickly. Keep a coastal walk up your sleeve for when the sun comes out, and open the list filtered by “Out of the rain” to sort these places from nearest to furthest with the “Near me” button.
