Бурда, Mountain range in Nové Zámky District, Slovakia.

Burda is a mountain range that runs along the Danube River in the Nové Zámky District with steep slopes covered by forests. The chain of hills forms a natural divide between the Slovak and Hungarian territories along the river.

The range is the Slovakian remnant of the Börzsöny volcanic massif, built of Miocene andesite and covered in places by loess. Two national nature reserves were declared here in 1966: Kováčovské kopce – juh (now Burdov, 364.14 ha) and Kováčovské kopce – sever (now Leliansky les, 198.74 ha). The southern reserve protects the richest thermophilous biocoenosis in Slovakia, including the northernmost occurrence of the Taurian hibiscus.

The dual naming in Slovak and Hungarian reflects the mixed heritage of this border region where two peoples have lived alongside each other. You can see this reflected in how locals and signage refer to the same places by different names.

Three marked hiking trails cross the range: red from Garamkövesd east over the Kovácspataki rocks to the former Kovácspatak railway stop, yellow from that stop east to the Kovácspatak resort, and blue north through Nagy-völgy to the Ipoly shelter. A 5 km nature trail with six stops and 220 m of ascent links Garamkövesd and Kovácspatak in about two hours.

The Danube River cuts through the mountains at one point creating a natural gateway called Vyšehradská brána that visitors often miss. This geological formation offers one of the most interesting views of how the river has shaped the landscape over time.
