Are you leaving for the day or more? If you are experienced, you certainly know what equipment to bring.
In any case, it is your feet that will carry you and you must therefore have suitable shoes. If you go for one or more nights outside, be aware that the gites usually have blankets to offer. But nothing beats the comfort of its own sleeping bag.
Take the sun very seriously and think about sunscreen, hat and glasses.
Showers may not be available daily. Remember to take baby wipes for the toilet. Toothbrush and toothpaste. Bottle of water.
Plan to face the sun, rain, cold, wind ... depending on the exit you have chosen.
