Sete on France 🇫🇷

Hello everyone!

I'm going to go with my husband to the city of Sete in France, relax on the beach and swim, can you tell me what interesting places you can visit there? Unfortunately, we don't have a car, but I don't think it will be a problem to travel by bus 🚌

We are going there for the first time, so I would like to ask those who know a little more, what is interesting there that could be visited? (We are like 28 and 30 yo)
