‘It certainly had some scary moments.’ That was le Fils Aixcentric’s take on the Via Ferrata at Cavaillon , even though he’s tried them 
out in the Alps. Meaning ‘iron way’, a Via Ferrata is a series of scrambles along the mountainside linked by metal ladders, hand-holds, bridges and ropes.
The Provencal one has two loops, one of which goes through a tunnel tight enough to necessitate taking a rucksack off. According to le Fils Aixcentric, just the first parcours is suitable for children over 10, as they need to be a certain height in order to reach hand-holds and so on. Adults can use both. ‘It’s interesting with nice plants along the way; but certainly a physical and mental challenge’. It’s free to use but there are charges for renting the safety harnesses and equipment that are needed.
Interestingly, it is the only one in Europe accessible on foot from a town centre, in this case the tourist office of Cavaillon. Details and 3 min film here:

Have you tried it? I have done both loops and loved it.
No I have neither the nerves nor the knees!
