Hello! It's great to hear that you're planning a visit to the beautiful cities of Valensole, Gordes, and Avignon in France. Here are some travel tips for you.

Best Time to Visit:
The best time to visit these destinations in France is typically between April and June, as well as September and October. In Valensole, specifically, you would ideally want to visit in late June or early July for the lavender season. Autumn is particularly beautiful in Gordes and Avignon.

Route and Accessibility:
Valensole, Gordes and Avignon are easily accessible by road. You can start your journey from Nice or Marseille, both of which have international airports. From there, you could rent a car or board a train to reach Avignon first, then Gordes and finally Valensole.

Accommodation and Booking:
The three cities offer a wide range of accommodation options, from luxury hotels to charming bed-and-breakfasts. Consider booking your accommodation in advance, especially during the peak tourist season. Online platforms such as Booking.com or Airbnb can offer a variety of choices based on your budget and preferences.

Clothing and Essentials:
Considering the weather during the ideal times to visit, light to medium clothing should suffice. Carry comfortable shoes for walking around the towns. Don't forget your sun protection (hat, sunglasses, sunscreen) as the sun can get quite strong. Always carry a water bottle to keep yourself hydrated.

Health and Safety:
France has an excellent healthcare system. However, it's advisable to get travel insurance covering health issues and accidents. If you're on prescription medication, ensure you bring enough to last your trip.

Local Etiquette and Respect:
French people appreciate courtesy, so please and thank you ('s'il vous plaît' and 'merci', respectively) are good to know. English is widely spoken but making an effort to communicate in French is often greatly appreciated. Ensure to respect local traditions and avoid loud behaviour.
