Trek into the wild corners wild camping on the way – Loads of great places to go – Glen Affric might be a good one – you can walk in or cycle in and camp – and climb a couple of mountains from your camp spot. Knoydart is great as well
Or base yourself in Fort William – get the train to corrour and walk back to fort William – can be done in a long day if you phone a taxi to meet you at the road end at fort williuam or do it with one overnight camp and that gets you thru some fantastic scenery
[controversial] If you have never ridden in Scotland a day at Glentress would be well worth it – you can mix an match trails to suit any skill level[/controversial]
natural riding – rothiemurcus perhaps? – and don’t forget the inshrioch tea room if in the area
Laggan is a nice wee trailcentre with a more natural feel to it than some again in a really nice area
Don’t be tempted to spend too much time driving – Glentress could be done on the way north of back south and then pick one or two areas and base yourself around there.
If you want t drive that far the north west coast is stunning – From Lochinver up to durness – the wee mad road thru inverpolly is an interesting experience 🙂 and stac pollaidhis a nice climb with stunning views. Good cycling / walking in torridon area as well
Take midge repellent – smidge is the new one of choice. and midge hoods
