Visit the Highlands. They are a beautiful set of mountains, and lots of history lies in those craggy rocks.
Speak with the locals. Scottish are friendly and open,and will often be willing to share a sip of guinness or a bite of haggis.
Eat dat haggis! Speaking of witch, the haggis is a historical food that is the food of champs.
Travel off the path. Once seeing Glasgow,Edinburgh, and seeing the locals, get away from the crowd,and travel to the mountains, see some scotch sheep.
Oh, also, you might want to dig through your put-away-for-summer rain clothes. Scotland is furiously windy and rainy
And definitely see famous old Loch Ness. its a great place, and your kid may be the first to capture Nessie. Let her go,though. don't damage Scotland's natural beauty by taking one of its most historical and legendary items.
