Zalakaros

Southwestern Hungarian spa town built around mineral-rich thermal water discovered while drilling for oil.

Zalakaros is a small spa town in southwestern Hungary, near Lake Balaton. The town's thermal water was discovered by accident in 1962, when drillers searching for oil hit a spring at 2,300 metres depth — the water comes up at 96°C and is rich in minerals.

The Gránit Thermal and Adventure Bath has grown steadily since the 1960s and now includes indoor and outdoor pools, water slides, a wellness centre, and treatment facilities. It draws a steady stream of visitors from Hungary, Austria, and Germany, many of them coming for multi-day cure programmes. The town has developed accordingly, with guesthouses, pensions, and restaurants lining the main streets.

Beyond the spa, Zalakaros is a quiet place. The surrounding Zala County countryside is gentle and green, with vineyards and small villages. The Kis-Balaton wetlands, an important bird habitat, are a short drive north. The town makes a reasonable base if you want to combine thermal bathing with exploring the western shore of Lake Balaton.

When to Go

The thermal baths operate year-round, which makes Zalakaros viable in any season. Spring and autumn are pleasant for the outdoor pools and the surrounding countryside. Summer brings more crowds and higher prices, especially in July and August when the outdoor adventure section is in full operation. Winter visits can be surprisingly enjoyable — the contrast between the cold air and the warm thermal pools has its own appeal, and the resort is quiet.

The Kis-Balaton wetlands are at their best for birds in April–May and August–September, when migrating species pass through in large numbers.
