Another lovely hike under the winter sun. Be careful as the ground is slippery in places, but otherwise the paths are very pleasant. And part of the lake is frozen over. Impressive!

February 22, 2025,Rund um die Olef-Talsperre

The dry, spring-like weather is crying out for movement. And so today we went around the Olef Dam near Hellenthal. 13.5 km was definitely enough for the start of the season. Luckily the birch catkins are not yet in full bloom. Visually, the paired flower heads are very attractive, even if they are "eye-catching" when exposed to a little more …

June 14, 2026,Oleftalsperre Runde von Hellenthal - Eifel 🌲🌳🇩🇪

After spending the night at the campsite "Naturcampinganlage Schafbachmühle", my companion and I met up with a friend who lives nearby. Together we walked a loop around the Olefsee and past the Oleftalsperre 😁
We started at the large, free parking lot directly at the dam.
It was a beautiful circular trail with good conversations and pleasant temperatures 😄🥾

November 27, 2024,🥾 Rund um die Oleftalsperre

Today I had a very special goal on my list: to hike all the way around the Oleftalsperre. 🏞️💧 To do this, I drove to Hellenthal 🚗, and from there I started the climb from the foot of the dam to the top. The first part was tough, because the gradient was quite steep - but I mastered it quickly …

Today I spontaneously drove to the Oleftalsperre in this wonderful weather.
The girls often had to be on a leash today because they constantly wanted to climb the steep slope to the water.
So it's a nice, leisurely round that can be walked without any difficulties.

Small circuit around the Oleftalsperre.
The path is largely flat; there is only a small climb to the height of the dam.
The dense vegetation only sporadically allows a clear view of the long reservoir.
