Loose the flash intro, I hate them, and all it does is involve yet another click and wait to get where you want to be.
You have no 'Home' link at the top of the page where it's needed.
As mentioned earlier, use normal text without making possible keywords <strong>. I don't think search engines are really going to take much notice of that - just ensure they're there and in the right context. Make link text the same size also.
The background to the text is a little....white. I find it easier to read if the brightness is toned down a little - maybe a delicate seamlessly tiled background more in keeping with the Scottish Highlands? Maybe a very faint, almost transparent image of pine forest? (NOT tartan!)
Your map. Gives the impression you could click on several different areas to zoom into those specific regions, which isnt so. I'd use the mulben.gif as the main map - although make it larger and more detailed, as it meant little to me as it was. Nice graphics, though.
Again, as already mentioned, check grammar, punctuation and spaces.
Regards, Andy.
