If you're looking to treat yourself to a little break with a bit more comfort, I recommend the Rothaarbad in Bad Berleburg.
Here, activity and relaxation combine in a very pleasant way. The bath offers an indoor pool open all year round with a sports pool, a warm variable-depth pool, and relaxation areas – complemented by an outdoor pool with a sunbathing lawn during the summer months.
I particularly like the sauna area with various saunas, a steam bath, and a relaxation room with a forest ambiance. After an active day outdoors, it's the perfect place to unwind and recharge.
For me, the Rothaarbad is an ideal complement to the many outdoor activities – quiet, versatile, and a great choice any time of year.
