If a hotel has a swank spa that administers treatments using ultra-expensive (and effective) Sisley products, it’s probably something special. And if those treatments come in a Victorian manse overlooking the placid waters of Kenmare Bay in Southwestern Ireland’s Ring of Kerry, it’s yet more likely to engage even the jaded traveler’s predilections for plush resorts. Kenmare Manor, a turn-of-the-19th-century stone building backed by patchwork hills and forests, looks like something out of a storybook. But it’s more than attractive: At SÁMAS spa, the treatments, which are indeed high-caliber, come with views of the misty woods (from the pool) and the bay and mountains (from the relaxation room). Staff are attentive to even tiny details, like buttery Irish shortbread at turndown. Breakfasts of smoked salmon and eggs and flaky scones are served by smartly dressed waiters rather than set out at a buffet. The hotel’s restaurant is known as one of the best in the country for wild-mushroom risotto and Kerry lamb loin with eucalyptus-flavored peas.
