I had good grounding in hill walking in my late teens, combined with rock climbing and by my 20s I was combining the two, mostly staying over night in barns, bunk houses or under canvas. When I came to walking in later life, I wound up my business 4 yrs short of the 2008 crash, but Mrs BWW continued to work. We did B&B's on her free days, which led to self catering cottages.
I was fairly confident that I knew all I needed to know about walking, it was these marvellous breaks that made me realise that there is far more to walking than I had assumed I then knew. It is the variety of terrain, combined with the freedom of the day that these often gorgeous locations allow, less likely to be influenced by recommendations about where you should go by well meaning locals, yet close enough to to get into the feel of the place.
We stayed in a converted manorial gate house in the Gatehouse of Fleet, I had done tons of preparation for The Galway Forest, but the weather made it chancy to get a day to take risks, but we were fortunate, a one day gap gave us the opportunity the Walk the Merrick and to find the Grey Man of Merrick. Mrs BWW had told our host that it was one of our aims during our week, the day after, when he came round and she told him we had done it, he said, "Lots of people say they are coming here to do that, but you are first to actually do it".
The cottage was beautifully done out, we climbed to the bedroom by a stone spiral stair case up a tower, decorated with a fantasy mural and had red squirrels feeding outside the kitchen window when we breakfasted. The furnishings were as similarly classy as the OP's photos and I think we negotiated an extra night outside the fixed weeks on the booking schedule. The nightly charge was similar to cheap B&B.
One of my abiding memories were the colours of the stone of the Solway Firth, when the weather was claggy, the close-ups were as vibrant as any of the distant views we might have been missing on hilltops, we even had a deserted island to explore. I put down a marker on the tideline as it was falling, had I not so, we would have spent the night on that island.
Sadly the one thing I did notice was the local walkers had really failed to develop routes in keeping with freedoms given to them by the 2003 Land Reform Act. We could have walked better routes low down, if there was a true understanding based on the intention of this law change.
That is just one experience of these marvelous examples of our developing hospitality trade, shame a properly evolving share of the countryside, they are situated in, is not keeping pace.
