I was riding up in the north west of Scotland this weekend and in the youth hostel at Gairloch I bumped into a guy from the Edinburgh Geological Society who runs geology themed walking holidays. That area is perfect for it – great riding and amazing geology, but you do have to know what you’re looking for.
Take Fisherfield – you’ve got some of the oldest rocks in the world (Lewisian Gneiss), then lovely red Torridon Sandstone sat on top of it and then on top of that quartzite caps that burn red in the light of a sunset. Amazing stuff, and the gneiss has big massive lumps of all sorts of stuff in it, and there’s also the Moine Thrust which has left an escarpment further up some of the glens. Some of the rocks you see in the rivers are fascinating – they really demonstrate just how violent the geological processes round there are.
But, while it’s a spectacular landscape, it takes some geological knowledge to enjoy it (I am a geologist) and you don’t really get the big single exciting feature to marvel at.
I’ll also throw Edinburgh and the Pentlands into the mix. Riding the Edinburgh Seven Hills you’re riding a group of extinct volcanoes with some really great features.
The Fife Coastal Path goes by some good caves and the Rock and Spindle, a volcanic plug sitting on a beach.
Scotland’s just full of stuff.
