These are on the unclassified road running round the Corniche de l’Amorique. Take the Locquirec to Plestin-les-Grèves road. Having crosses the estuary, take the first road on the left which runs along the east side of Corniche de l’Amorique. The baths are a short distance along this road. There is a small (unsigned) car park immediately above the baths with a larger (signed) car park a bit further on. Walk back through the trees for the baths.
The baths are in coniferous woodland just above the beach. The original bath house was built around 100AD and had a cold room and hot room with plunge pool. During the 2ndC AD the bath house was extended and and extra hot bath and furnace were added. The main furnace area was extended as a fuel store. The site was abandoned in the 4thC and robbed for building stone before disappearing under sand dunes.
The walls stand about 4’ high in places. The cold bath was at the end with the two hot pools by the side of the beach. The stoke holes, hypocaust and remains of wall ducts can still be seen.
Interesting, especially if you like Roman remains, but not a ‘must see’.
