The wooden footbridge was pulled into place by a fallen tree during the last flood. It is still not accessible.

When the water level is high, the jetty is often flooded. The water masses are raging! This time it hit the jetty. Damaged by a fallen tree trunk.

Here you are in the water castle area of Switzerland. A few meters downstream, the Limmat flows into the Aare. A few hundred meters upstream, the Reuss flows into the Aare. The Reuss and the Limmat flow into the Aare on the right bank. It is always nice to stop here, and every time you see a different picture.

You can step over this small bridge, switch off, watch the water masses... That's where the Limmat meets the Aare. The ducks that live here offer you a relaxed game with the rushing water. Like a kitty corner for the ducks!!! And for us an oasis of well-being. Welcome!

Really a very nice, but sometimes a strenuous tour. At least for people who don't hike that much. Really good shoes and a sufficient and good physical condition are important. Then you can go. It is interesting and in good weather there are MEGA GREAT views. There's also a lot of rest areas. All in all, SUPER BEAUTIFUL.

Legend of Egelsee: Among the knights who once lived in our land there were many godless and violent people. No traveler on the road, no seed in the field, no ox at the plow and no carving in the trough were safe from them. They robbed, burned and murdered whatever fell into their hands. Such a monster of a knight also lived in a castle on the Heitersberg. His name was Riko. But his castle was called Bauernweh because it only brought misery and misfortune to the farmers in the area. For the knight went out every day with wild dogs and rough companions in arms and returned to his castle in the evening with heavy robbery. On the way back from one such foray, they once came to the farm of a widow who had not been able to pay the interest on time. The monsters packed up the woman's belongings, drove her and her children out of the house and set it on fire. The mother only wanted to take a handful of flour with her to make porridge for her youngest child. Then the knight tore the child from her arms and threw it into the flames. "Now there's no need for porridge anymore," he sneered and ran off with his flock. The mother knelt in agony by the burning house and begged heaven to have mercy on the people and end their misery. And heaven heard the lamentation of the unhappy mother. That same night a terrible storm hit the area. Lightning flashed down on the castle without interruption, and with a mighty crash it sank, along with all hands, a hundred fathoms deep into the abyss. The following morning a deep, black lake lay where she had sunk. For a long time he was feared and avoided by people. It's the Egelsee
