Slovenia is a small wellness powerhouse: short distances, well-kept resorts and quality thermal waters. Here are our favourite destinations for a weekend of relaxation, all reachable by coach.

Terme Olimia

A modern, well-kept thermal complex in the heart of eastern Slovenia. Heated thermal pools, Finnish saunas, a Turkish bath and bright relaxation areas. Ideal for a short 2–3 day getaway.

Rimske Terme

A Roman-inspired complex with elegant colonnades, panoramic pools and natural thermal water. A weekend here is the right choice for those seeking a more refined stay.

Terme Sveti Martin

Although technically in Croatia, just a few kilometres from the border, Sveti Martin is one of the most elegant wellness resorts in the area: perfect for a longer stay combining thermal spas, nature and gastronomy.
