This is why I think Highlands Links is one of the greatest course routings I have ever seen. Yes, it is a long walk, with a few substantial hikes between holes, and yes, there are a couple of tough climbs (the ascent of the sixteenth fairway is the hardest for me, because of where it comes in the round).
But it is also a _fantastic_ walk. At no point do you feel that you are being taken round the houses for no good reason, as is so often the case on residential courses. Thompson reveals the property to you, bit by bit, via some brilliant golf holes. By the time you get to the top of the valley, on the tenth tee, you feel completely out in the wilderness. And then, when he really couldn't get a good golf hole in the terrain, he takes you on a sylvan stroll down the riverbank.
Sometimes I reflect on the course, and wonder whether tacking back up 14 was necessary - I've always felt in the middle of a run for home by that point, and it seems a little odd to turn back on yourself. But it gets you 15, 16 and 17, all superb holes. And you return to the clubhouse, tired yes, but exhilarated. To create such a great walk, and such wonderful golf, on a site like that, is true genius imo.
