Huge, very interesting fortress with a great view. Bring plenty of time and go into the cellar. Attention! The tickets have to be bought at the bottom of the mountain. There is a kiosk right by the fortress.

August 15, 2021,Auf zum Hohentwiel

Anyone who believes there are no volcanoes in Germany is wrong. Today I hiked one. The Hohentwiel used to be almost one, luckily it never really broke out, but the pressure formed today's formation. Very interesting mountain and the old castle ruins are so interesting that I can only recommend it. Unfortunately, a violent storm forced me to break off, …

I haven't been up there in a long time, the goats 🐐 🐐 were new to me 🤣
It's always worth a trip, it's simply beautiful there 😍 and despite the great weather, there aren't many people around 👍

With an area of 9 hectares, Hohentwiel is one of the largest fortress ruins in Germany. The view over Lake Constance, the hills of Thurgau and the mountain range of the Alps is beautiful. The fertile soil on the volcanic rock makes the Hohentwiel the highest vineyard in Germany.

We took a trip to the ruins, as the weather isn't always so kind to us in the mornings. But I'm glad the sun didn't come out until we were descending.
A worthwhile destination with beautiful views. You should be in good shape, as the climb is steep. There's a snack bar halfway up with fresh, cold drinks and small …

After I circled the Hohentwiel the day before yesterday, we set out to explore the fortress ourselves today. You have to buy the tickets at the parking lot. The fortress ruin itself is absolutely impressive, if only because of its size. The individual parts of the building and their function are explained by boards everywhere. If you want to delve …

A wonderful tour on the Hohentwiel. You pay 5 € entry but it's absolutely worth it. Fantastic view, a lot to see and always opportunities to sit down to enjoy the view, take a snack, etc.

Absolutely recommendable, even if the climb is very steep. From the parking lot at the restaurant you have to reckon with two hours for the ascent and descent and the great views.
