Best Things to Do in Lithuania – Lithuania, the largest Baltic state, attracts visitors with its diverse attractions: Vilnius’s historic Old Town, walkable Kaunas, and the scenic coast of Klaipėda and the Curonian Spit. Travelers should plan carefully, as seeing all three cities in a short time is challenging. Vilnius is ideal for first-timers due to its airport and attractions, while Kaunas offers a quieter experience. The best visit period is late May through early September for favorable weather. Key highlights include Vilnius Old Town, Gediminas Tower, and Trakai Island Castle.
