Trakai by train: the castle on the lake and Karaite kibinai

Trakai is the nearest day trip from Vilnius: the train takes about half an hour. See the Island Castle on Lake Galvė, walk to the Peninsula Castle and look into the Karaite kenesa, and try kibinai for lunch. It suits any time of year, but the opening hours of the castles and museums change with the season and get shorter by one hour on the eve of holidays. The day plan fits into one day: a morning train, the castle, lunch and the return in the evening. Practical tip: it is about 3.1 km (42 min) on foot from the railway station to the Island Castle, so allow more time or take a bus.
