In June 2012, I went on a three weeks-long trip through the Baltics. During this time, I spent just over a week in Lithuania, and visited quite a large number of places: Vilnius, the Curonian Spit, as well as Dzūkija and Aukštaitija National Parks (among others) were part of my itinerary.
A short travel diary of this trip can be found in my blog. Furthermore, there is a small photo album.
