The best way to get to Podpeca is by car. It is some 120km north-east from Ljubljana and lies in a quite remote area. The closest (4km) bigger town is Crna (na Koroskem). Once you get there just watch for the signs ''GRADOVI'' which lead to Podpeca and Park Kralja Matjaza. But be aware that the last part of the road is not the best (macadam). It's usualy coverd with snow and thus very slippery. If you car doesn't have proper winter equipment it's better to leave it somewhere along the road, on the organised parking lots and take the van (service organized just for the castle building event).
The event always takes place on the last weekend in january. The saturday is the day of the competition. Teams start building their castles at 10h and have 6 hours to complete them. It's fun walking around, observing the progress, which teams have problems. They will also try to bribe you so you'd vote for their castle :-). At 18h the winners are announced by King Matjaz himself. He also presents his beloved Alenchitsa, who he chooses among the visitors.
The sunday program is more children oriented. It's more relaxed.
The castles then remain in King Matjaz's Park in Podpeca as long as the weather alows it.
The entrance fee to the King Matjaz's park is 600 sit and the ticket is valid for both days. With the ticket you also get a piece of paper where you write down your favourite castle in competition. You also get a postcard which you can send without stamp.
But once you are inside, you don't need the entrance ticket any more. So, if there are more of you, you can sand on out to sell the ticket (but one) to the people that are just arriving. With one remianing that person can get back in again. We did so this year, sold the ticket with lower price. Funny thing, that this was acctually suggested by the people that were selling tickets.
