I seem to bring up our holiday to the Isle of Skye whenever I can and I would highly recommend you take a week to visit there at some point. There's incredible landscapes around every corner and if you like being outdoors, then it's definitely the place for you. You can read more about my Skye holiday and see photos, just in case you need more persuasion to visit!
Really though, as a family, we've seen a lot of Scotland. We've been to Ayr, Isle of Arran, Inverness, Glasgow (recently for AC/DC actually) all the way up to Wick and John O' Groats and then there's all the time I'm spending in Edinburgh this month too.
We've spent time in the Lake District and I was there filming our dissertation too. Further south we've visited Weymouth, Dorchester and places in Devon and I had a little work trip to Brighton back in April. Cornwall is somewhere on our list and hopefully, if we find somewhere to stay, we'll be heading down there for the end of the summer.
If you are heading to Cornwall, locals recommend you visit Kynance Cove Beach and if you fancy, give surfing a go! Maybe watersports aren't your thing, relax and enjoy cream tea - whether it's the Devonshire way with cream first then jam, or Cornish with the jam first and clotted cream second. It's fairly easy to spot which way I go for...
