The Erdbachschwinde natural monument (officially designated as "Einflussstelle des Erdbaches" in the Lahn-Dill-Kreis protected landscape area) is one of the most fascinating geological phenomena of the Westerwald. The karst sinkhole, known as "Kleingrubenloch", is located in the historic town center of Erdbach and was placed under legal protection as early as 1938. Geological peculiarity The centerpiece of the natural monument is a so-called ponor (sinkhole). At this point, the Erdbach stream, which flows above ground, completely disappears into around ten known rock fissures and karst springs in the Devonian limestone. The water plunges into the depths here and passes through the Erdbach Cave, which, with a depth of almost 100 meters, is considered the deepest known cave system in Hesse. After an underground flow of about 1.5 kilometers and a travel time of around 14 to 34 hours, the stream finally re-emerges at daylight in a lower-lying quarry. Technical additions and speleology Since the natural rock funnels are easily blocked by washed-in wood and debris during heavy rainfall, severe floods occurred regularly in the village in the past. To ensure drainage, workers dug an artificial relief shaft into the hard rock as early as 1928. This artificial access enabled speleologists in the 1990s to comprehensively explore the branched and scientifically highly significant Breitscheid-Erdbach cave system. Tourist development Today, the Erdbachschwinde is a central destination for nature enthusiasts. It is located directly on the GeoRoute of the Breitscheid karst and cave educational trail, which connects the natural monument directly with the prehistoric stone chamber graves and the neighboring Erdbachium museum. Information boards on site explain to visitors the chemical weathering processes through which the water has carved this impressive underground path into the reef limestone over millennia.

Remnants from the time when siderite was mined in several pits and tunnels in this region. The Clara Tunnel led from the valley to the Leo Shaft.

Slightly hidden, the Clara Tunnel is located in the quarry above the old stone crushing plant, on the bike path to the chapel.
