We are planning a trip to Glen Forsa in July. We will be in the area for a week, island hopping. I have allowed 2 weeks, so if the weather is at all duff, we will hire a car and sight-see. As fisbangwollop says, the weather can be brilliant or dodgy. Mind you, it is important to have a plan B when flying and it helps if you have an instrument rating (I have). But in Scotland, some clouds have hard centres and quite often there is nasty ice about. I remember, years ago flying down a valley on the west coast and entered cloud. Lucky for me both burners took me to 20,000 feet in no time at all. Sadly now, my puddle-jumper cannot do that. Scotland, especially the west coast, is magical. But one needs to know what one is doing. That mountain ridge looks wonderful, but what about the downdraft of 1500 fpm?
