Flying in the Highlands and Islands, particularly in low wing loaded aircraft like microlights and the Kitfox, can be bumpy at times.
And the wind does not even have to be that strong. My most difficult approach (2) and landing (1) (*) at Glenforsa was last Friday with no more than a 15 knot crosswind (from the SE, of course)!
I have sometimes had to climb to 7-9000 feet to get above the turbulence particularly south of Inverness is a southerly/south-westerly.
Having said that, the worst turbulence I have ever experienced was in the valley north-east of Ambleside in the Lake District.
Also got an American book on mountain flying somewhere: remember tips like crossing ridges at an angle and flying on the upwind side of the valley but if the worst happens, slowing down, tightening your straps but not over-controlling and turning downwind to get out of it. Invaluable advice.
(*) Actually (2) after a big bounce following the second approach!
