The main reason people come to Dolenjske Toplice is this attractive, well-run spa centre. The Lagoon has outdoor (May to September) and indoor (year-round) pools with thermal water between 27°C and 32°C; the Oasis section hosts saunas, a Japanese sweat bath and a chill-out terrace; and the swish Treatment section is where you go for pampering facials and rejuvenating massages.

For nonguests as well as those staying at Hotel Balnea there are day-long relaxation packages available, combining lagoon access, sauna, massage and beauty treatment.

As you drive into town, the centre is in pretty parkland just north of the hotels – it's connected to the Hotel Balnea by a walkway.
