The Arda is a tributary of Evros river - the largest one. Its springs are located up the mountains of the Rhodope Mountains in Bulgaria, and most of it crosses the neighboring country. It flows eastward and enters the Greek territory from the northern part of Orestiada. Αfter bathing at the spot where the rivers Ardas, Evros and Tonsus meet, Orestes is said to have been cleansed of the crime of matricide, for which he had been pursued by the Furies. With dense forests of alders, willows, poplars, hornbeams, field elms, plane trees, and various other species of plants growing along its banks, the Arda is proved to be an important habitat of the area with rich flora.  The fauna of Arda is particularly impressive, with various species (predators, smaller birds, reptiles, mammals, and fish) finding shelter on its banks and in its waters. Over the years, large land improvement and irrigation projects have been constructed to supply the surrounding areas with water and avoid flooding. Ardas Festival takes place in the area every year. naturagraeca Municipality of Orestiada

Dadia is a settlement on the slope of Gibrena peak. It is located inside the magnificent National Park of Dadia-Lefkimmi-Soufli Forest. During the Ottoman period, the village was called Tsiam-Kebir or Tsamkioi, meaning "pine tree" in Turkish,  due to the existence of many pine trees in the area. Dadia was named after the Greek word δαδί (dadi), meaning the resin-filled wood that comes from the pine tree employed as a means of lighting and kindling. According to folk tradition, the residents of Dadia settled here to avoid an epidemic in their homeland, a city located on a hill, on the bank of the Evros, the ruins of which can still be traced at the point where the river meets the Maggazi stream.

City in the region of Evros, 2 km away from the Greek-Turkish border. It was named after the double walls of its castle (Kale) or, according to another version, after the two opposite fortified cities (one on Kale and the other one on the opposite hill, Agia Petra). The city is built at the point where the rivers Evros and Erythropotamos meet, 40 km away from the Bulgarian border, and it hosts the headquarters of the Diocese of Didymoteicho, Orestiada and Soufli as well as the Muftia of Didymoteicho. The history of the city dates to the Neolithic period. It used to be the administrative and military base of the Byzantine Empire and became its capital three times. Later on, it became the first Ottoman capital in European territory. Didymoteicho was officially united with Greece by the Treaty of Sevres in 1920. Today, most of the Muslim minority belong to the Roma community. After the Greco-Turkish War (1919–1922), refugees from the Asia Minor, Eastern Thrace and Eastern Romilia settled here. There is also an Armenian community in the city. Didymoteicho has several important sights, indicative of the long history of the city. Plotinoupolis, the ancient city on the hill of Agia Petra, with impressive findings such as the Golden Bust of the emperor Septimius Severus and a Roman mosaic with mythological representations.

It was also the birthplace of Ioannis III Vatatzis and Ioannis V Palaiologos, as well as the headquarters of the emperors Ioannis III Palaiologos and Ioannis VI Kantakouzinos. The Armenian church Surp Kevork (Agios Georgios), the Agora Gate (central castle gate), the Princess Tower, Agia Aikaterini church, the burial chapel of the Palaiologos era, the church of Christ the Savior in the Castle of Agios Athanasios, the church of the Assumption of Virgin, and several springs are some of the most interesting attractions in the city.
