Actually, I was wondering about this. I'd heard the midges are a nightmare. How bad is it really, does it vary by location, and can anything be done to mitigate the problem?
My house mate has just come back from walking the West Highland Way (walked the whole thing over two weeks). He said that midges weren't that much of a problem (could be a little too early, I don't know) but he had huge problems with ticks!! He camped and was infested by them on numerous occasions. Had to stop off at a B & B one night and get the landlady to help him remove them off his back!!! She then gave him a dettol bath!! ;o) So maybe pack a tick remover!!
They tend to follow me everywhere but I found that going mid-May it wasn't too much of a problem. I went once in early June and they were starting to build up - especially at night.
