Clava is definitely worth seeing - sometimes it's busy, sometimes it's quiet. if you hang around for a while, you'll probably get a bit of time to yourself:

this last one isn't particularly interesting, but it is just round the corner from the fantastic Moulin Inn! you should give us a shout when you come over, as I'm sure a few of the Scottish Megaraks will grace you with their presence
