bismi asks about a wedding done by a priest (i.e. church wedding), miri and Loni missed the answer a bit (they talk about registrar - i.e. civil wedding).
My wife and I had a super experience - civil wedding in the valley, then right away to St. Vid (above Zg. Tuhinj - accessible on foot /guests able to walk on foot should go on foot!/ and by car - you have to think about that if you have some "veteran" in the family) - there church wedding.
Unfortunately the priest was later transferred to another parish (not because of our wedding
). Last year he died, so I can't ask him for info. It was really great.
If this variant interests you, inquire with the priest in Zg. Tuhinj.
Of course church weddings at Kredarica, Molička planina ... are great - but, as I wrote. You can't take some "veterans" who walk with difficulty there.
