The park was established in 1997 through the merger of three smaller protected landscape areas.
It contains the highest peak of the Börzsöny Mountains, Csóványos, at 938 meters.
The Danube Bend (Dunakanyar) area features specific volcanic geological formations resulting from Miocene-era activity.
The park preserves the Pálvölgyi cave system, one of Hungary's longest labyrinthine cave networks.
It serves as a critical biological corridor for large carnivores like lynx and wolves returning to the region.
The park includes the Ramsar site of the Ipoly Valley, a vital wetland for migratory waterfowl.
Danube-Ipoly National Park covers 60,314 hectares, spanning the hilly regions of the Pilis, Visegrád, and Börzsöny mountains. The park protects the unique ecological convergence zone where the Danube bends through the Carpathian Basin. Nagymaros serves as a gateway to the park's eastern section, providing access to extensive forested hiking trails. Within the park, visitors find medieval castle remnants, including the ruins at Hegyes-tető and the proximity to the Visegrád Citadel. The landscape features deep valleys, limestone gorges, and diverse karst topography. The park is home to protected species including the Hungarian meadow viper and various raptors. Its varied elevation provides significant microclimatic differences between the riverbank and mountain peaks. The area remains a primary site for geological research and conservation of Central European deciduous forests.
The Julianus Lookout Tower (Julianus-kilátó) on Hegyes-tető for panoramic views of the Danube Bend.
Bring a detailed topographical map or GPS device, as cell service can be intermittent in dense valleys.
Pack sufficient water and supplies, as facilities are scarce once you leave the village trailheads.
Stick strictly to marked trails to avoid disrupting protected wildlife habitats.
Attempting unmarked shortcuts on steep limestone terrain; leaving trash on trails.
Some interior forest roads are restricted to vehicles; specific caves may close for bat hibernation periods.
Hiking boots with ankle support are essential; quiet behavior is required to observe local wildlife.
