It can be difficult to breathe within the walls of some stodgy, high class, five star hotels. But when you visit CastleMartyr Resort in Cork County, Ireland, the fresh air is plentiful. The resort consists of a striking 17th century country manor house that sits adjacent to the ruins of an 800-year-old-castle. Hit the spa to relax, play golf on their Ron Kirby-designed course, or just stroll the grounds and take in the expansive, beautiful surroundings. They even encourage you to take their Irish Setters, who welcome you upon arrival, for a walk around the hotel acreage.
