I visited this tentative site in August 2016. Having missed the group visit and after reading that most tours from Vilnius depart after 5pm, I decided to visit in the late afternoon. It turned out to be a wise choice as the sunlight for photography is great in the afternoon, parking was less of a hassle and it wasn't too crowded. The castle interior is nothing special and not worth visiting. What surprised me was that the castle fortifications or high walls are only round the entrance while on the rear part of the island there are no fortifications! This is clearly seen if you go on a 1 hour boat trip or if you hire a paddle boat or canoe yourself. At sunset, there are hot air balloon rides over the castle which added to the overall romantic ambience. I enjoyed the sunset view from my deckchair at the Bona Restaurant sipping cocktails and tasting some delicious kibinas, local Karaite pastries.
