March 18, 2023,MTB Rundtour zum Schloss Altenklingen bei Kaiserwetter

Partly traily round trip in glorious weather to Altenklingen Castle, I left out the Altenburg ruins that belonged to it today. If you want to learn more about it, I'll link a video at the end.

The oldest castle of the Lords of Klingen in the vicinity was the Altenburg near Märstetten, which was abandoned around 1200 and is now …

March 27, 2022,Trailige MTB Seerückenrundtour mit viel Bärlauch bei Kaiserwetter

I'll start today's tour description with a quote: "When the well is dry, you only appreciate the water" and so the trails in the region are currently "fart-dry".

Today there was a lot of movement in the woods and so I was drawn away from the mainstream on trails and rather unknown paths and that fitted perfectly.

Today, in sunny weather, we went back to the Seerücken and to the great forests according to the motto: "Feel the healing power of the forest to open your senses and draw energy".

Once in Kemmental, the trail leads to the Schleifenrain ruins and then on to the Altenburg ruins, one of the oldest ruins in the canton of Thurgau. …

Originally a special kind of hike was planned for the anniversary today, but unfortunately nobody was able to come, so there is a short and nice bike tour to the Schleifenrain ruins and those who read to the end can reward themselves.

February 18, 2024,Nebelige Rundtour nach Märstetten ab Ermatingen

I'll start with a saying: "The main reason for STRESS is daily contact with idiots". Before I describe today's tour, I will discuss a draft law that is boldly called "Komoot Paragraph" 33.

I will quote briefly: “What is new and confusing is the so-called “Komoot paragraph” 33 of the speaker template, which only allows the digital recording of routes …

November 21, 2022,3 Ruinen MTB Rundtour Castell - Schleifenrain - Altenburg mit viel Panorama und Geschichte

I'll try to be brief today, and a phrase comes to mind: "Briefness is the spice" :-)

"The sweetness lies in brevity" comes from Shakespeare's Hamlet. The play about the Danish prince was first performed in 1603. And in the piece there is the following text passage: "Because brevity is the soul of wit, prolixity is the body and expression, …

June 23, 2023,Lässige MTB Rundtour etwas ins Hinterland und zum Schloss Altenklingen mit schönem Panorama

Today a very spontaneous, casual MTB tour without a lot of frills and with pleasant temperatures. The Bommer Weiher looked special today, no bikers - no hikers and it has really great water lilies.

Something historical about Altenklingen Castle ........
