When people visit the Eifel, they’re usually occupied with mountain biking, walking or other activities, but if you want a bit of real relaxation on your holiday, you’d be hard-pressed to do better than a visit to the Thermen & Badewelt Euskirchen. It is a wellness centre and palm and swimming paradise with tropical atmospheres. The sub-tropical swimming paradise contains more than 500 real palm trees and the water is 33°C.
