Llandeilo Town Twinning Association visited their Breton counterparts in Le Conquet over the Bank Holiday weekend.
This trip marked the 22nd visit since the union was formed.
Members stayed as house guests with French twinning members, learning about their way of life, and forming strong bonds.
The hosts arranged a programme of banquets, music, and cabaret entertainment, as well as trips to town markets, a museum, and other parts of Bretagne.
Committee member Christoph Fischer said: "After the night crossing on the ferry I felt tired and on the back foot.
"But then we had so much fun, my host and myself were the last to leave the restaurant on the last night despite my resolve for just one early night."
Llandeilo mayor Charlotte Morgan and mayoress Charlotte Walker joined the group, meeting with Le Conquet mayor Jean Luc Milin to discuss the similarities and differences between the two towns.
Mayoress Walker led a Welsh sing-off between the two groups, with musicians from Brittany encouraging people to dance.
Mayor Morgan said: "I did not know what to expect, but what I discovered was a quirky and truly unique French-English-Breton-Welsh blended community, that I believe we should not only embrace but celebrate."
One of the founding members, Mair, who had missed previous trips due to health issues, joined at the last minute and reunited with a Breton founding member.
Twinning chairperson Linda Durgan said: "It’s been encouraging that there is also an influx of new members with children.
"There should be a few more young twinners coming over to Llandeilo next time and Llandeilo Youth Club has been invited to the Le Conquet camping site next year."
Social secretary Brenda Vautier added: "Our French counterparts are expected over Easter 2025, but we will organise a few more social and fundraising events, and hopefully an exchange of exhibitions."
