Rogaška Slatina, magnesium water and hand-made crystal

A spa town in figures

According to SURS, Rogaška Slatina has 5,256 residents and its municipality 11,679 on 1 January 2026, across 41 settlements. In 2025 it logged 47,814 arrivals and 195,231 overnight stays, more than four nights per visitor. That makes it one of the big spa towns of Savinjska, and it carries the bronze Slovenia Green Destination award.

A 17th-century legend says Pegasus discovered the spring, which is why the winged horse is the town’s symbol, with a statue by the sculptor Vasilij Ćetković Vasko.

What’s special about Donat Mg water?

The Donat Mg spring is what makes Rogaška Slatina unique, according to the tourist board, because its water contains more magnesium than any other in the world. It’s taken as a drinking cure or in mineral baths, and the Rogaška Medical Centre offers balneotherapy, physiotherapy and diagnostics. There are also pools and wellness centres that combine the mineral water with thermal water.

The park, the promenade and the Grand Hotel

The heart of the resort is its park, covering 10,000 m², with 4,500 box plants, 7,400 annuals, 7,500 perennials and 700 roses, and a promenade shaded by sycamores and horse chestnuts between Secession buildings. The former Health Centre is now the Grand Hotel Rogaška, with the hall that captivated the emperors of Austria-Hungary, where Anna’s Ball is held, and the Crystal Hall with its hand-made chandeliers.

The crystal works and museum

The Rogaška glassworks is, according to the tourist board, the world’s largest hand-made crystal producer, with the most glass blowers and cutters, and it’s open to visitors. Anna’s Mansion serves as the town museum, with collections on glass, local history, the park and the water.

Surroundings and fitting it in

Nine trails lead to the nearby peaks, and Mt Boč is a landscape park and Natura 2000 site, with the pasque flower as its emblem. The Rogaška Wine Road calls at tourist farms, where you can taste local wine alongside cured meats, bread, juices and pastries. The local sweet is mlinci potica, three to five thin flatbreads layered with walnut or egg-and-cheese filling, once baked only for Easter in a wood-fired oven. The Gaja association still makes it to the old recipe. Around town you’ll also spot rare trees such as ginkgo and service trees. By bike, a route links the town with Podčetrtek via Lake Vonarje. For me, Rogaška deserves two nights, and it pairs well with the other spas in Slovenia along the Sotla valley. On the road to Celje, Šentjur has the house of the Ipavec composers and the Rifnik archaeological park.
