Biržai one of the oldest towns in Lithuania, is counting five hundred years already. Situated between two rivers Apaščia and Agluona, and two lakes Širvėna and Kilučiai, Biržai is exceptionally rich with natural phenomena.
The nature in Biržai region has always been very special: at one place or another, the ground collapses, creating karst sinkholes. There are more than 9,000 such sinkholes in the Biržai region. The most famous one, Cow’s Cave in Karajamiškiai Natural Park, is the most researched geological monument in northern Lithuania.
If you climb to the top of the 32-meter-tall observation tower in Kirkliai village, you will be able to observe the breath-taking view of 30 karst lakes. Sometimes in summer, when the natural circumstances fit together, the lakes appear in different colours.
Širvėna Lake, one of the region’s most beautiful lakes, is home to Lithuania’s longest pedestrian bridge. It connects Biržai City and Astravas Manor, which belonged to the influential Radvilos and Tiškevičiai families up until the 20th century.
The bridge is especially loved and often visited by fishermen, wedding guests, and local people, who enjoy the tranquility of the lake as well as the beautiful sight of the town.
