your memory serves you well. Wully. Ardnamurchan was beautiful but the beaches are scarce. We were only over for a couple of days so could only explore a wee corner. Sanna bay was our kiting spot and it was excellent - big steady winds and loads of scudding. but it isn't big and only suitable for static flying. The sand is the of the gorgeous West Coast variety and was nice and hard so might suit a board but just not enough room to get going with a buggy (especially as you have a fairly long walk in to the beach)
Sooooo ..... for a romantic holiday, 10/10. For the next TK expedition 1/10! Fun in discovering and flying a kite on an empty beach 20/10 !!!
