This sprawling complex of swimming pools truly offers every type of water fun. The highlight of the spa is its natural “black” water, which is a blistering 72 degrees Celsius at the source but thankfully cools down to a tolerable 34 degrees in the pools. If the black water isn’t hot enough for you, check out the saunas or solarium. Not the most stylish or modern spa in Slovenia, but Terme 3000 still creates a fun, family atmosphere. Catering mostly to German-speaking tourists, most information is only in that language, but the staff will do their best to make you feel at home. Located about 200km east of Ljubljana in the Prekmurje region, it about as far as you can get from the capital without leaving the country.
