I like achnabobane farmhouse, it’s a between the fort and spean bridge, really close to nevis range, in the middle of the deer farm. It’s a proper old school B&B run by these lovely old stereotypes- retired army guy who as far as I can tell does **** all, 70 year old lady who clearly works non stop all day cleaning the house and chopping logs and killing deer with a cleaver. The accomodation’s a little basic feeling, it’s all pretty old and small, but it’s nice- charming rather than shagged out. And they have a sort of creepy shrine to Fabien Barel in the living room. There’s no secure bike storage, but you don’t need it frankly.
Also, they’re inexplicably secretive so you can often book there when everything else within a hundred miles is full.
Downside- I almost got my car irremovably stuck in their car park, it was like some sort of logic puzzle. “Well I got it into this gap so it must go out…” Luckily the 70 year old lady carried it out for me in one hand while gutting a pig with the other.
