One of the best ways to work up an appetite for an opulent Christmas lunch has to be to go for a swim. This time of year is very much associated with indulgence, but it can also be a time for self care and wellbeing as well. A swim is a joyful part of a holiday, and there’s no reason it can’t be part of a festive escape either. Choose from historic hotels with pools in former ballrooms, to spa hotels with complete thermal suites including Jacuzzis, hydrotherapy, saunas and steam rooms. Whether you’re looking for an adult-only spa break complete with all the pampering you could ask for, or a family friendly getaway with space for the kids to splash around, these are the hotels for Christmas that come complete with an indoor pool.
