Into the Curfsgroeve, an old marl quarry

In the wooded slopes between Berg and Meerssen lies the Curfsgroeve, where marl was dug for more than 70 years. From the viewpoint you look over 50-metre cliffs and the deep quarry floor; goats keep the scrub in check. Part of the quarry is closed to the public because of falling rocks and its rare wildlife.

There are no paths in the quarry: walking boots are required, a stick helps with balance, and the walk is not suitable for anyone unsteady on their feet because of the steep, slippery slopes. From 10 am to noon, starting at the De Nachtegaal inn, Gemeentebroek 6. Tickets 7.50 euros, children under 12 free (link below). The organiser's page is in Dutch.
