Kaunas being one of the former Capitals of Lithuania, is a fascinating City, which is having a re-birth! The Kaunas Castle (Pilis) is a must, as is a stroll down Laisves Aleju (Freedom Alley) to the Rotuse (Town Hall and Square).
If you are a basketball fan, a visit to Zalgiris Arena is a must, as undoubtably Kaunas Zalgiris fans are the most passionate and vocal in all of Europe!
We visited in the month of May but would probably enjoy visiting at any time of the year. There was a good variety of museums, churches, historic buildings and other atractions to keep a variety of interests contented.
