May can be the best month in Scotland, ofetn dry and sunny without ever being the hottest. However we have had wetter Mays recently and this year snow is still falling on high ground. In fact I am going to get a late ski this week.
On a recent trip into The National Park I had a nice walk into Lairig Ghru and it got quite snowy at the high point. We could see a storm rolling up behind us from the Spey Valley. We descended back down into Spring!
Crail is 2hrs drive from the National Park, 2 hrs 45 from Aviemore
