At Kirkilai village was built tower, which is shaped like a canoe. Tower height - almost 32 meters, observation deck area - about 30 square meters. Climb up to the observation tower offers stunning views - 30 water full of sinkholes, called Kirkilai Reserve lakes, with a diameter - about 35 m and more. As nowhere, most sinkholes in this Reserve are slipped below the ground waters level, therefore sinkholes have turned into small lakes, swamps.
