The Măcin Mountains are among the oldest mountains in Romania, located in Tulcea County. They are known for their beautiful rocky landscapes, hiking trails, and rich variety of plants and wildlife.

Insula Cailor, or Horses Island, is a small wild island on the Danube near Galați, close to the confluence with the Prut, where Romania, Moldova, and Ukraine are relatively close together.

The Danube Delta has three main arms: Chilia, the northernmost and largest; Sulina, the central and main navigable arm; and Sfantu Gheorghe, the southernmost and more natural arm. Together, they carry the Danube’s waters to the Black Sea and shape the unique landscape of the delta.

The Braila Bridge, also known as the Golden Gate Bridge over the Danube, is one of Romania’s most impressive modern structures. Opened in 2023, it is the longest suspension bridge in Romania, stretching about 2 km across the Danube and connecting Brăila and Tulcea counties.
