At the side of glass-like Owenmore River, near the foot of Ben Lettery, this gabled manor house looks too good to be true. It’s a postcard setting, perfect in almost every way. The 16th-century building, once the seat of the O’Flaherty chieftains, is now a casually elegant hotel. Lounges have towering ceilings and warming fireplaces. Guest rooms are just modern enough, in muted shades of cream and toast; many have fireplaces—all have orthopedic mattresses. The river is known for its trout and salmon, and your catch can be weighed up each evening in the wood-paneled Fishermen’s Bar. Dinner in the beautiful Owenmore Restaurant is a highlight of any stay.
