On Saturday, Nibulon’s tour boats start taking tourists from Mykolaiv down the Southern Bug and across the Dnipro Gulf to Kinburn Spit, a remote peninsula featuring a 122 square km national park with sandy beaches and wetlands rich in bird life. In the five years since the loss of Crimea, Nibulon, a commercial grain shipper, has turned river and coastal cruises into a flourishing summer sideline business. The boat trip from Mykolaiv to Nibulon’s private pier on Kinburn Spit takes two hours and costs $9.
