Yes, we also visited this waterfall on May 28, 2024. Unfortunately, it started to rain halfway through, but that didn't stop us from doing the hike. There was plenty of water! It's a very beautiful hike and I highly recommend it!

Impressive holes in the rock, I wouldn't call them a cave in the strictest sense. But worth a detour.

If you need some refreshment, this is the place for you. The washed out rocks form small pools that are ideal for swimming and you can even slide on some of the smooth rocks.

THE TROLL CAVES The first service was held here in 1911. A large number of people rowed to the lakeshore for this service. Then there was a break in service until 1988. The new parish pastor, Mr. Torfinn Moen, made this cave service an annual tradition. About 10,000 years ago, during the last Ice Age, and before the land rose, these caves were carved out by water.
