The Troll church consists of three exciting limestone grottos with underground streams and waterfalls. The two lower grottos have beautiful waterfalls that cascade 14 metres down into a white marble pool. The uppermost one consists of long underground passages. On the surface to the west of the uppermost grotto there is a fishing lake with white marble "jetties". The mountain behind the Trolls' church is very distinctive, with jagged points and spires. You will need wellington boots and a torch for this trip. It is about an hour and a half's walk up a steep path from the car park on the RV 64 road.
