Brubble approx. every 40 min

The Geyser in Wallenborn is a cold water geyser that erupts every 35 minutes. So if you just missed the eruption (or want to see it again), you only have to wait half an hour and the spectacle begins again. The physical basics around the geyser are sufficiently explained on the display boards all around. The Wallende Born is something like the smaller brother of the cold water geyser in Andernach, because the physical principle is the same. In the past, you could visit the geyser free of charge, but today you have to pay a small fee, which is manageable, and if you haven't seen something like this before, you should take a look (it's always cheaper than the Andernach geyser).

The enchanting Meerfelder Maar lies in the middle of the largest Maar funnel in the Eifel. This maar is at least 30,000 years old and takes up about half the space of the maar funnel. The idyllic village of Meerfeld nestles against the steep southern slopes of the other half.

The existence of the village Birresborn was documented for the first time in 721. The name "Birgisburias" can be translated as "good source". Numerous finds in the area of the source evidence that this source was already known to the Romans. The Linden source is located on the ''Kyllradweg'', directly at the L24.

On to the "Brubbel": https://www.eifel.info/a-wallender-born

The cold water geyser, which is actually a drilled mofette, shoots up a water fountain every 35 minutes. Interesting. A visit to this geyser can easily be combined with the HeimatSspur hiking trail "Wallenborner Weg".

"... A seemingly peaceful fountain awakens and begins to bubble. Suddenly a fountain of 9°C cold water shoots into the sky, bubbling up for six minutes. Then the spook is over just as quickly as the "bubbling" like that Locals affectionately call their phenomenon, calms down. The basis for this natural spectacle is a carbonated spring, one of which there are hundreds in the Eifel. In the early 1930s, Wallenborn wanted to use this industrially and started drilling. But when they tried, chunks of earth and water flew around their ears. They had stumbled upon a chamber in which rising CO2 was collecting and pouring out with force and water to the surface. The fact that the "Brubbel" still spits out at such regular intervals today can be explained by means of a comparison: Similar to a soda bottle that is shaken, the pressure in the underground chamber increases. At some point – after 35 minutes to be precise – this exceeds the pressure of the water column above it. The Wallende Born was born - the cold water geyser in the Eifel. ..." https://www.eifel.info/a-wallender-born
