Several companies offer cruises of various length, from one hour to a full day, either in the Bassin de Thau or at sea. Sète Croisière is one of them. We did not try it and I cannot advise it more than any other.
However, I have a doubt about boats that offer a sea view through a glass bottom or glass sides: I doubt that the water might be clear enough to allow much sight. Consider the cruise for the above water sights, not for the under water sights.
We took the local train to the ancient city of Agde.It was a dull day,(one of many this trip), so decided to go further afield.
The journey took 8 minutes and went all along the edge of the Etang de Thau.Fare was 5 Euros.The area here produces the Listel wine and salt, from the salt flats along this spit of land between Sete and Agde.
We were able to wander through the tiny streets of the vielle ville and see more than if it were hot and sunny.
We found an out of the way restaurant- packed with French people so decided to have lunch- as they were doing.We had been having our main meal in the evenings, but I thought we'd be better off doing it the French way then having a snack at night.
The meal was superb.
Prawn cocktail, served on a huge square glass plate- big unshelled prawns on a bed of delicious salad, with divine dressing.
Followed by entrecote, frites and salad
Followed by ice cream and coffee- for 10Euros!
The ices were served in interesting glasses that resembled old fashioned hip baths!
Such great value.We sat and had our leisurely meal, just like the locals, under the awning outside.Which was just as well as it poured down just as we took our seats.Miserable weather- but wonderful food- so we were happy.
A little,2 compartment train runs to Montpellier every 15 minutes,approx.It has a huge toilet right in the middle of the compartment,which can be a bit smelly!
Strange place to put it?
Mainline,TGV trains run to Carcassonne,Beziers,etc.from Sete.It takes about an hour to Carcassonne.Lovely picturesque ride.
They also go east to Avignon,Arles,Nimes,etc.
Sete is a place well-served by transport facilities for visitors without cars.
Prices are reasonable-Sete to Montpellier,return,is about 5 GBP.
Local buses run frequently and cover the town and outskirts area.
Buses start at the station and call at many stops through the town,alongside the canal and go to the beaches,about 10 minutes away.
One does a round trip,stopping through the town,going up Mont St.Clair and going to the hypermarket,Auchan,which is handy for self-caterers.A good way to see the area as well.
Timetables can be obtained from the Tourist Office at the "Mole"(jetty) end of the main street.
