At the edge of the large lake lies a tranquil jetty, a spot that immediately invites you to pause for a moment. The wooden platform extends slightly out into the water, offering a beautiful, unobstructed view of the wide lake. Here, the scents of pine forest and fresh water merge, and all you hear is the gentle lapping against the jetty. It's a place where dragonflies skim low over the surface and waterfowl regularly glide by. In calm weather, the lake transforms into a mirror, sharply reflecting clouds and treetops.

A ride on the little train is a wonderful surprise for all ages. And those who want and are able can climb the tower, where a magnificent view of the former coal-mining region awaits.

The 31-meter-high observation tower is a replica of the drilling rig André Dumont used to extract the first coal in 1901. This tower is located at the As station and is free to visit. It offers a panoramic view of the station site and the surrounding National Park.
