A small tour along the "Castle Trail" along a river called Lauter. The first ruins on the way, St. Ruprecht, could almost be missed if there wasn't a sign. Not really any walls left. Monsberg Ruins though still has a bit of a tower, some walls and part of a cellar. The most impressive former castle is Wartstein with a rebuilt tower overlooking the valley and the region. The way back was along the river where a heron tried to fly away from us but constantly managed to fly into the direction in which we were going so he started and landed at least 10 times until he realized that it would be better to fly upriver.
