    St. Jansboschgroeve V and VI are the two easternmost of the five quarries, and also the lowest lying.

    The St. Jansboschgroeve V is the easternmost of the five St. Jansboschgroeven. Small quarry, the opening of which is well hidden in the forest. The entrance is closed with a grille to let bats through. The tunnel itself has a length of about 20 meters.

    The St. Jansboschgroeve IV is the second lowest located quarry (after quarry V) of the five St. Jansboschgroeven. The entrance is fenced off. 30, 40 and 50 meters to the northwest are quarry III, II and I respectively, and 30 meters to the northeast is quarry V. Single tunnel of about 9 meters in length, entrance is fairly silted up with soil.

      One of the St. Jansbosch quarries in the area. You can look into the quarry but not into it.
      The quarry is closed with a fence so that bats can get in, but we humans have to stay outside.

        Deep in the tranquil woods near Valkenburg lie St. Jansbosch Quarries IV and V—two old marl quarries that recall the days when marl was still intensively mined here. The entrances, partially hidden among ferns and vegetation, exude a mysterious atmosphere and reveal the intertwining of nature and history here. These quarries were part of a larger network of underground passages once essential for the construction of many Limburg monuments. Today, they are silent monuments to craftsmanship and transience, offering a special place of peace and wonder during a walk through the woods.
