The Romans already enjoyed the warm mineral waters of Aachen and Charlemagne famously had his palace (and now even more famous church) built here in part due to the presence of the hot water. However, the current Carolus Therme is a modern facility with all the latest day spa facilities.

The Carolus Therme day spa is divided into four sections: the Thermal World (Thermalwelt), Sauna World (Saunawelt), Indulgence World (Verwöhnwelt), and Gourmet World (Schlemmerwelt). The sauna world is completely nude (FKK / Textilfrei) while swimming clothes are obligatory in the thermal baths.

The Thermalwelt Hot Water Pools in Aachen

The Thermalwelt with its various thermal baths is the main draw for visitors to the Carolus Therme day spa in Aachen. Various medical cures are claimed for the mineral-rich waters but most visitors simply enjoy relaxing in the hot water, Jacuzzis, water jets, and other water features.

The Carolus spa has five interior baths with temperatures ranging from 18°C to 46°C. The main pool is 34°C. The two exterior swimming pools are 32°C and up to 1.3 m deep. A beach area and outdoor sunning areas are open when the weather allows.

Free aqua gymnastics are offered up to six times per day but only once on weekends.

Due to the high mineral contents of the water, children under six are not allowed into the day spa at all.

The sauna world of the Carolus Therme day spa has 15 different saunas and steam rooms, a sauna lake, and a Japanese garden.

The sauna world is divided into further sections and spread over several floors:

  • The Baltic Sauna landscape has two dry saunas (70 – 100°C).
  • The Sauna Garden has four further saunas (60-100°C) and a warm outdoor pool.
  • The Oriental World of Baths has eight steam rooms or hamam stations
  • The Feminarium has a further sauna and steam room open to woman only

As is the common practice in Germany, the sauna area is completely in the nude and genders are mixed. Robes or towels may be used when moving between saunas.

Spa Treatments at the Carolus Therme

The Carolus Therme offers the full range of typical day spa treatments to visitors – not all require admission fees to the rest of the spa. In addition to massages and beauty treatments, private Jacuzzis are also available.

Spa treatments are best reserved in advance but may also be booked on arrival if appointments are still available.

Gourmet World at the Carolus Therme

The Gourmet World of the Carolus Therme has three separate restaurants:

  • The Bella Vista offers light meals and snacks with views of the main pool.
  • The Lemon Grass offers Asian and European dishes and is only open to visitors to the sauna world.
  • Mediterraneo serves Mediterranean food and is also accessible to diners not visiting the spa. A beer garden opens when the weather allows.
