@hypolite Oh I can't see that in my notifications
If you're traveling by train or car your route from Skye to Glasgow is sure to take you through Fort William, and basically Glen Nevis is accessed from the town. It's gorgeous and you have a really good chance of seeing Highland Cows in the glen.
Edit: This is one of them!

@hypolite Also that's a pretty good loop and you should have a good chance of seeing much loveliness (there's a good reliable spot for dolphins not far from Inverness if that's of interest too).
