So..soooo.. lucky you are..
.. love to visit Scotland.... perhaps even catch that.. Loch Ness monster of yours..lol.... question are there truly lots of castles to visit.. open to the public that is... and do they charge admission...?
Only Loch Ness monster that I saw today. was eating a Subway sandwich in Inverness! Ha ha. There's tons of places you can go in Scotland, as my country is steeped in history, but if you come visit Edinburgh Castle, the Edinburgh Vaults ( Spookiest place I've ever been! ) Loch Lomond, Oban, The Isle of Skye, Stirling Castle and Wallace Monument, Forth Rail bridge, Isle of Arran, Inverness and Defo Glasgow! Some places charge you, but a lot of places and Castles, etc, are free to visit around the Glasgow area, ok?
