I visited Croatian island Krk during the recent summer holidays. Arma fans might know the island as Everon, the main island of the original Operation Flashpoint.
It was amazing experience to be there and visit locations you remember from the game. Castle isn’t there (sadly), hills are a bit smaller and the island is much larger than you would anticipate. It still resambles Everon in many aspects. You can check below a few comparision photos of Krk and Everon.
