For the ultimate indulgent spa day, head to ESPA in the Park at Whittlebury Park in Northamptonshire. This lavish spa day includes full access to the state-of-the-art leisure club, modern gym, 19-metre pool and heat and ice facilities, which include a sauna, aromatherapy crystal steam room, ice cave, caldarium and hydrotherapy pool. For even more decadence, head to a private treatment room, where an expert therapist will take care of the rest. Indulge in a 110-minute ESPA Bespoke Massage and Facial each, using pure aromatherapy blends to relieve tension, balance your mind and leave your skin glowing. Add the finishing touch with a scrumptious two-course buffet lunch to relish.
