Start at Grantown on Spey and go down the River Spey for the Whiskey Road. Gorgeous country.
A chunk due south of Inverness.
The travel I pray I have before I die is to start in the Cairngorms and move NNW to to coast. I'm not sure why but this has been a dream of mine for almost 30 years and I'm not even Scottish!
Plans are in the making to spend my 50th there and and I will have to figure out how to apologize to my Welsh ancestors that will be spinning in their graves.
