The Dnipro-Bug estuary was formed as a result of the transgression of the Black Sea in the lower reaches of the Dnieper and the Southern Bug. The estuary is connected to the Black Sea by a 3.6 km wide strait (between the Ochakov cape and the Kinburn spit). The southern shores are low, sandy; northern, mostly high (up to 20-35 m), composed of clay-sandy rocks, only in some areas there are sand-shell spits. The bottom near the braids is sandy, at a depth is covered with loamy-sand silts.
Olvia National Historical and Archaeological Site
Olvia translates as “happy” in ancient Greek. This is the official name of the city certified in the decrees it issued, in inscriptions on coins and in most of written chronicles. Having survived for almost a thousand years, its name did not disappear, after all. Today, Olvia is a national historical and archaeological reserve that attracts thousands of visitors every year.
The Natural Reserve "Yelanetsky steppe" is a protected area in Novoodeskiy and Yelanetskiy Counties of Mykolayiv Oblast. The reserve was established on July 17, 1996 and covers 1,675.7 hectares. As the first and, so far, only steppe reserve in Right-Bank Ukraine, the Yelanetskiy Steppe Reserve is intended to preserve and restore natural steppe systems in this part of Ukraine. It is also meant to protect the largest virgin steppe in the Northwest Black Sea region. Efforts are being made to preserve and restore fescue-grass steppe, which is not available in other protected areas of Ukraine.

The Kinburnska Kosa
The Kinburnska Kosa is a protected peninsula located in Ochakiv and Berezan Counties in Mykolayiv Oblast between the Dnipro-Buh estuary and the Black Sea. The Park covers 35,223.15 hectares.
