Some 'other' stuff to do....
Moustiers is very touristy, however the Chapel above the town is worth visiting and has an interesting side hike.
As you walk up the paved zig zags look for a small contour path that breaks out left (going up) follow this for a while and look right, use your climbers nose and you will access a series of ladders that lead to the top of the pinnacle from which the cable that supports the star is suspended. It is not a via ferratta, it was quite rickety when I found it some years ago, and I don't know its current state or if you're supposed/allowed up it, but...... It make Moustiers a bit more spicy.
A road heads north out of La Palud that leads to a small abandoned village Chatueneuf de Moustiers, follow the road out of the village(it an old Roman road I believe. It eventually goes beneath some crags which have a chapel in a cave the base of the walls, Chappelle de Notre Dame. At the back of the cave is a small squirm that leads up to the upper cave.
Opposite , to the North is a substantial hill, Le Grande Mourre, this is a good day hike. We did it from Chateuneuf, my recollection was that it went on a bit!
Folks have mentioned the gorge walks, the most impressive section is from Couloir Samsone to Chalet Malines, One way - either way. You can usually get a taxi back to the start point, I've usually hitched and got a lift. It's a great hike, take a torch for the tunnels.
There's an observatory in the hills behind La Palud that used to be open to the public some nights.
You can hire pedalos and canoes at the Lac St Croix, and head up the gorge under some impressive cliffs, proper DWS! and picnic.
As a complete contrast to the craziness of the gorge, you could have a day visit to Annot in the hills West of Castellane, wooded single and multipitch climbing on Lime/sandstone which has huge Ammonites embedded in it.
