We came to Klevan to see the Czartoryski Castle (1561). The old castle is in awful condition today, looks like ruins of a town after bombing. The place is not very touristic, more extreme. I didn't take any pictures inside the castle, as after various "Soviet" institutions there is just nothing to shoot. But for those who like abandoned buildings this place is perfect.
Unfortunately, the government forgot about this castle, although main parts remain in a normal condition - walls, entrance gate, and bridge.
There is one more interesting place in Klevan, "Tunnel Lubvi" (Tunnel of Love). We visited it in May 2013.
Getting there: From Rivne take either any bus to Lutsk from the bus station or a bus to Klevan from the train station. You can also go by train from Kyiv.
