Hi Flo-
<<" I have also been told that the nature trail is not so difficult and there are some other hikes around the area.">>
Swiss standards for "not so difficult" can be extremely steep trails for long distances. Alpenroses description should not be ignored or discarded.
In that region of the world, peasants and farmers used to walk routinely over the hills from valley to valley, or down to Sion.
May I suggest that you look into the region Evolene, les Hauderes, la Forclaz?

It is accessible from Sion by regular bus.
Many many years ago I took a bus in from Sion and walked from La Forclaz to Evolene on a trail above the road, up on the side of the valley. Easy walk. The farmers were cutting hay by hand with scythes, in old style peasant dress. The storehouses were up on stilts with "mazots" ....the thin circular stone disks characteristic of the Valais architecture.
The villages look like they might be large enough to have a store and a place to eat, but, at least then, they were very definitely not crowded, modernized, or full of rich peoples ski chateaux.
Times have changed, and ski chateaux have sprung up everywhere all over Switzerland, like some kind of fungus, but If I were seeking the experience you describe, I'd at least look into that area.

The villages have been there a long, long time, and were not created purely for skiers.
I really don't know much about the area, but it was very peaceful
