The authenticity of the geobotanical walks in Hévíz is ensured by the knowledgeable experts at Hévízi Túrák, who not only know but also love this region. According to Zoltán Samu, geobotanical tour guide, examining human presence and impact is essential to understanding the landscape. “As a nature conservation engineer, I’m primarily interested in the relationship between the landscape and the people living in it. To me, the landscape is empty without people.” This perspective permeates the tours as a whole.

Geobotanical tours are structured around a deliberate thematic framework: we follow the path of water from deep underground to the surface, explore the forest’s elevation gradients, and finally marvel at the rich wildlife of the lake and canal.

The essence of the geobotanical approach is complexity: understanding how geological foundations determine botanical values and how these, in turn, influence the landscape as a whole.

During the tour, we’ll also learn about past mistakes –such as the drop in water levels caused by mining – and the tremendous efforts that succeeded in saving the lake from drying up. The expert-led tour helps you notice even the smallest details – a unique insect, a rare species of mushroom, or the life going on inside a piece of deadwood – that a casual hiker might easily overlook.

In addition to the well-known data on water temperature and depth, we also show how the unique spring system shapes the surrounding soil conditions and the vegetation that grows there. Or what happened to the 12,000-year-old rainwater on its journey to Lake Hévíz.

The 4.4-hectare lake lies in a peat basin, which is also a rare phenomenon for hot springs and holds many surprises. This peat layer is not only the raw material for mud packs – which are important in medicine – but also acts as a kind of filter and biological buffer that regulates the distribution of gases and minerals rising from the springs, thereby providing unique living conditions.

Yes, and we’ll even explain its function in detail. The forest belt encircling Lake Hévíz is much more than just an aesthetic green ring; this area is the key to the lake’s ecological survival, which is why the geobotanical tour route passes through it.

One of Hévíz’s most distinctive sights is the dense layer of mist floating above the water, which we call the “mist blanket.” This phenomenon is of critical importance for maintaining the water’s temperature, especially during the colder months. The mist blanket could not form without the protective forest, which is why proper management of the forest is of paramount importance.

On our geobotanical tours, we demonstrate how a forest can be regenerated in several stages without compromising its ecological functions – that is, in accordance with the principle of the “perpetual forest.”

The most exciting feature of the Water Lily Nature Trail is the 15-meter-high canopy observation tower, which offers a unique panoramic view of the forest and the lake.

The sight of water lilies – pink, purple, and white – blooming along the nature trail is breathtaking in every season. The native whitewater lilies are found primarily in the drainage channels, while the pink ones are found at the lake bath. During the walks, you’ll also learn why it’s important to protect these plants and how they help maintain water quality.

As you walk the nature trail, the guide will explain why it’s forbidden to release any animals or plants into the lake or its surroundings, and what irreversible damage even a single pair of “innocent” little fish can cause if set free. Here you can also encounter red bass, Yucatan toothcarp, and various tropical bass species, which, although colourful and interesting, are actually causing the destruction of the native fauna.

One of the tour’s most important goals is to raise awareness: to help participants understand that protecting nature begins with responsible human behaviour.

The hikes are generally 3 kilometres long and take about 2 to 2.5 hours at a comfortable pace. The terrain is not difficult, therefore everyone – from preschoolers to seniors – can enjoy them.

Advance registration with the tour guide is required to participate (https://www.facebook.com/heviziturak). Participation fees have been set to be affordable for families: the program is free for children under 10, and those between the ages of 10 and 16 can purchase discounted tickets.

As for gear, we recommend wearing layers appropriate for the weather and closed-toe, comfortable walking shoes. Since the nature trail and the protected forest can be quite wet in places, slightly water-resistant footwear can come in handy.

The Hévíz Thermal Lake is an internationally renowned spa center where you can enjoy a variety of treatments, ranging from weight baths to mud wraps, though simply bathing among the water lilies floating on the lake is a special experience in itself.

The Hévíz Farmers’ Market is a must-see for food lovers; here, on Tuesday and Saturday mornings and Thursday afternoons, you can purchase fresh produce from local farmers, ranging from cheeses and smoked meats to honey.

Nature lovers, meanwhile, should explore the hidden gems near the Balaton Uplands National Park, such as the Kis-Balaton area or the lookout points in the Keszthely Mountains, which offer further exciting hiking opportunities.
