caravaning in Scotland

[Benspickup]

This summer, we're considering travelling up to Scotland for a 2 week break. It's a considerable distance for us living in sunny Lincolnshire. We're a family with one child at 4 and the other at 2.
We enjoy the outdoors and walking but is there munch for the little ones?
We have family that come from the west cost of Scotland but we're not overly fussed where we go

Any words of advice are greatly received

Also we take twiglet the labrador with us but most places are dog friendly
