One part of France I try and visit at least twice a year is the Languedoc area in the South of France. I love the Spring and summer weather down on the South coast and with the vineyards, beaches and local villages which I drive around and see. It is like visiting old friends now when going to many of these places.
Sete - is a lovely little town and with a waterway going through its heart, making for a very scenic location. The beach of Sete on the coast is also quite relaxing and provides lovedlty beach walks.
Agde - I love going also to the naturist resort Cap d'Agde each summer with my wife. With many French people as I am told, there is a certain enigma about the resort, but thousands of French, British, Australian, American and people from countries worldwide do visit each summer.
What makes the Langeudoc area also pretty handy is the closeness to the Spanish border, given that i do love also to pop down to Barcelona for a few days each year.
If you have never been to the Languedoc area I recommend popping down if you have the chance. Flights into Beziers or Montpellier should suffice or you can come down by train.
