Which resort to choose with children

With kids, age is everything. With babies under one year old, almost any resort works year-round: the water is warm, the air is mild, and parents can take turns going to treatments. In summer, choose resorts by the sea or with a large water park: Terme Čatež, Talaso Strunjan, and Terme Olimia.

Teenagers will find winter Rogla near Terme Zreče more interesting, where it's easy to get started on skis. The best season for a trip with kids is summer, from June to October: you'll have time to swim in the sea, in pools, and in mountain lakes.

When to go

Slovenia's thermal resorts operate year-round, and the medical facilities are designed for all seasons. In summer you swim in the sea and mountain lakes, and in winter you combine treatments with skiing. Modern hotels and dining cater to guests of any age.

High season is the period from June to October, when the sea warms up to a comfortable temperature. From November to April, resorts are less crowded, package prices are lower, and there are almost no lines for treatments.
