Armathwaite Hall Hotel & Spa
£££A 400-acre lakeside estate near Keswick, dog-friendly, with a 16-metre infinity pool overlooking Bassenthwaite Lake and the fells.
The consensus
Armathwaite Hall sits on a 400-acre estate on the shore of Bassenthwaite Lake near Keswick, dog-friendly throughout and built around a spa whose 16-metre infinity pool looks straight out over the lake to the fells beyond. Alongside the infinity pool, the spa runs to a hydrotherapy pool, sauna, aroma room, steam room and outdoor hot tub, and rooms start from around £211 a night. Both TripAdvisor and the independent Hotel Guru review are consistently positive, and the spa and its infinity-pool view are the single most repeated highlight across reviews — nothing resembling a significant, recurring complaint turned up in the review sampling here, which is unusual enough among spa hotels on this coast to be worth noting plainly rather than dressing up further. It's also one of the better-established venues on the voucher platforms, with packages listed directly through both Buyagift and Red Letter Days.
