Nice daytrip to take the bus from Oslo to Drobak and then the boat to the Fortress. Nice place to stroll around, look at the scenery and the old fortress building. There's a nice restaurant with a beautiful view of the fjord.

Lot's of history. As you walk thru the fortress they are many informational displays. Pictures and artifacts line the walls, and historical papers are abundant.

You climb up to the fortress in ten minutes walk along a narrow road but can also get on a fancy tourist little train; once you get to the main stone entrance you have to be lucky that there are no private events inside, otherwise...More
