Discover Komárno District: fortress, thermal waters and nature

When planning a hotel stay in Komárno District, you can start by choosing a destination based on a specific interest: fortress and Roman history, thermal waters, astronomy, nature or cycling. The destinations mentioned offer different points of interest, from buildings in Komárno to an observatory, a ship mill and protected wetlands.

Fortress, city gates and Roman history

The so-called Old Fortress in Komárno was built in the 16th century on the site of a medieval castle. The fortress in Komárno is part of the most extensive fortress system in Central Europe, which stretches across the territory of Slovakia and Hungary. The historic entrance gates connect the historic centre with Nádvorie Európy; each bears the name of a Hungarian ruler. The fortress is open to the general public year-round. Check the latest visitor information before your visit.

The western section of the Danube Limes ran for almost 600 km from Bad Gögging in Germany, through Austria, to Iža in Slovakia. Along the way, it followed the northern and eastern borders of the Roman provinces of Raetia, Noricum and northern Pannonia. In Iža, visitors to the Kelemantia Roman and Ethnographic Museum can also be admitted outside regular opening hours by prior arrangement.

Thermal waters in Komárno and Nesvady

The thermal spa in Komárno draws thermal water from a borehole 1,060 metres deep. The water emerges at a temperature of 45.2 °C and is directed into indoor and selected outdoor pools. In Nesvady, Thermál Nesvady uses geothermal water that emerges from a depth of 1,504 metres at 62 °C. The municipal website, updated on 20 August 2026, lists the spa as open year-round. The children's pool for children up to six years old is seasonal. These differences may be important for your plans; check the latest information on pool operations before visiting.

Observatory and ship mill

The history of the Hurbanovo Observatory dates back to 1871. It is open to the public during the day and in the evening, and also offers night-sky observations. The visitor offer includes an individual tour of the permanent exhibition at the M. T. Konkoly Museum. Check visiting hours before travelling.

The ship mill in Kolárovo is the last surviving example of a floating mill and the only ship mill in Slovakia. The mill houses the Water Milling Museum. Visitor information dated 26 May 2026 lists daily visiting hours from 10 am to 5 pm and guided tours every 15 minutes. Check these times again before travelling.

Wetlands and a cycling route along the Danube

Číčovské mŕtve rameno lies partly within the cadastral area of the municipality of Číčov in Komárno District and partly within the cadastral area of Kľúčovec in Dunajská Streda District. It is part of the Dunajské luhy Protected Landscape Area, which covers a total of 12,284.5 ha. This protected area forms a substantial part of the Dunajské luhy Ramsar site, which covers a total of 14,488 ha. The oxbow area is home to rare aquatic and wetland communities and is designated as a habitat of international importance for waterbirds. Ostrovné lúky is an important breeding and survival habitat for the red-footed falcon (Falco vespertinus).

For cycling travellers, the Bratislava–Štúrovo section of EuroVelo 6 is a practical planning reference: the easy road route along the Danube is 168 km long and passes through Komárno. Check the surface condition and signage before setting off.

Find a hotel to suit your travel plans
