A day trip pairing the fairytale island castle of Trakai with the sombre Paneriai memorial on the edge of Vilnius, where tens of thousands were killed during the Second World War. The contrast makes for a thoughtful outing: the restored red-brick castle on Lake Galve, then the forest memorial and its history. Transport from Vilnius is included, and the tour balances the region’s medieval grandeur with an honest account of its darker past.
