ケルペン（アイフェル）のおすすめウォーキング＆ハイキングルート

The karstified limestone cliffs are the first highlight on the path from the parking lot to the waterfall. Here, the stream has carved its way through the limestone, creating the rock face. The limestone originated as a deposit of dead marine organisms on the seabed of a shallow ocean that covered this area millions of years ago. Later, the ground was uplifted by tectonic processes. Limestone reacts with acid and is therefore dissolved by rainwater and surface water, which is slightly carbonated due to the CO2 in the air. This process creates weathered formations and caves. The formation of the Dreimühlen Waterfall is also related to this process.

Beautiful rock face to see.

There is a bridge nowadays.

Imposing limestone wall behind the Nohner Mill

Here, the Eifelsteig trail climbs steep steps past Kerpen Castle. A magnificent sight during the dandelion bloom 👌

Great volcanic crater that you can drive into through the tunnel

There is a new bridge here now, so you can cross without getting your feet wet 😉
