Campervan trip to Cornwall - any top tips of places to visit?

[MellowYellow0]

We’re hiring a campervan from Glasgow and considering heading down to Cornwall, 1st - 11th July. I have 5 year old twins and a dog and we’re looking for any top recommendations from the community about MUST SEE places, things to do or any events that might be happening that we should go to.

Your suggestions would be greatly welcome ❤️ Thank you ❤️
