Dunsthöhle Bad Pyrmont
Cave Bad Pyrmont · Weser Uplands · Lower Saxony
Not a stalactite, but gas: in a former red sandstone quarry, carbon dioxide escapes from underground and collects as an invisible lake at the bottom of the chamber, which was vaulted in 1720. The tour guides demonstrate this with experiments; Goethe had it demonstrated to him in 1801.
Visits are by guided tour only; tickets can be purchased online or by cashless payment on site, or in cash at the Tourist Information Centre on Europa-Platz. Children aged 6 and over; no pets. dunsthoehle.de

How this directory is made
It only lists places you can actually visit in 2026: show caves with guided tours, show mines, walk-in tunnels and bunkers. Museums without a way underground are left out, and so are sites that have closed. Prices, opening hours and temperatures come from the operators, and every entry names its source. If something could not be confirmed, it is missing rather than guessed. Place names stay in German, as they appear on signs and tickets.
What to expect underground
Underground it is the same temperature all year – between 3 and 20 °C at the places listed. Bring a jacket even in high summer, and sturdy shoes: paths are often wet and slippery. Most guided tours in Germany are in German only; many sites offer English leaflets or audio guides, so ask at the ticket desk. With a pushchair or wheelchair, use the filters above – far from every site is accessible.
