The trouble is that I have not set foot in Caledonia for twenty-eight years. On my first cycling trip in 1984, I bought two cards: South Scotland and northern Scotland, both of 1/200 000th, very accurate. They even included the arrows indicating the slopes, it was very convenient bike.
Alas these Michelin maps do not exist today and the only cards with other publishers scales by bringing are printed on both sides, not practical at all and quite imprecise.
This Michelin map is 1/400 000th but is very detailed: I noticed that they had added a bridge linking the Isle of Skye Kyle of Lochalsh, free and more (I guess the attendance of Island had to be affected). The "single track" roads (not to be confused with single malt) and passing places are always well marked. I have recounted, no missing loch but there is much more busy roads (I hope that drivers have become more bicycle-friendly because at the time ...)
Care should be taken to be careful when unfolding the map (the central folds being a bit blurry) failing to end up with a map ... in tatters!
