Spa Eastman is the place that put Eastman on many Quebec travellers' mental map. It is a large countryside wellness estate with thermotherapy, treatments, classes, food, and trails through its wooded grounds.
Treat it as a day-use spa rather than a sight. If that is what you want, it can be the whole reason to come; if you are not interested in soaking, treatments, or a quiet wellness day, spend your time on the village trails instead.
