The spindly, neo-Gothic turret of this 1897 hotel stands like a beacon overlooking Dundrum Bay. The surroundings are certainly dramatic, but inside this is a relaxing, luxurious place. Bedrooms are good-sized and modern; many have views of the bay and Mourne Mountains. Executive bedrooms are bigger and—a bonus if you’re visiting during a rare heatwave—have air conditioning. The excellent spa has a long list of treatments, from Ayurvedic regimens to hot stone massages and full-body salt scrubs. (Prices aren’t cheap, however—expect to pay between £75 and £170 for a 1- to 2-hour signature treatment.) The two restaurants are the formal Oak Room and the more relaxed Percy French. Dinner/bed-and-breakfast packages offer good savings.
