Right after sunrise, the bugs tend to be a bit sleepier than around noon.
Valensole was the first place we ever took a drone to. We used a rented drone from GearFlix and loved it so much I bought a drone on my own afterwards. The lavender fields are amazing for taking some drone shots, but only use it right after sunrise. There are many bees and bugs around the fields who will attack the drone (it was a true bug massacre). Right after sunrise, the bugs tend to be a bit sleepier than around noon.
