If you aren't paying attention, you could get stuck by a sharp object sticking out of the inner wall of the belfry. My daughter narrowly missed one such sharp object as she tried to avoid having her picture taken.
I really enjoyed the freedom to be able to explore monuments and historical structures throughout Montenegro. In the US, there is so much litigation, that many "unstable" monuments or even monuments with pointy things in them are off limits. We could climb structures in Montenegro that we couldn't climb in the US, even if they existed there.
Unless you are under 3 feet tall, you'll have to get on your hands and knees and crawl during some parts of the climb up the inside of the belfry at Perast. At least the stairs had reasonably stable guard rails, albeit a bit rusty in spots.
No problems - we made it up to the top and back without any mishaps. On the way up we saw some holes and heard squeaky noises inside. Squeak squeak. First we thought maybe they were rats, but decided they were swallows.
If you want to go to the islands of Sv.Djordje and Gospa od Škrpjela, be prepared to wait for the boat! The boat drivers will tell you "I'll be there in 5 minutes!" but Montenegrin 5 min. is at least half an hour... They seem to live in another system of reference. ;) You can find them later on just around the courner sipping coffee or beer with other boat drivers. Laziness is key word there! They are even lazy to take the money!!! Incredible!
