Access to certain areas might be restricted during winter to protect these colonies, so it's advisable to check specific site information before planning a winter visit.

The caves around Liège are primarily formed within limestone plateaus, a result of the region's varied topography. This geological composition has led to the formation of natural grottoes and extensive underground quarries from marl exploitation. You can observe ancient flints, chalk deposits, and the effects of water erosion, such as in the Chawresse valley where the stream disappears underground into cavities.

For beginners, the Thier des Vignes Flint Caves offer a good starting point. They feature more than 10 cave entrances along a path, which are not deep and run along the slope, making them relatively accessible for a first exploration.

The Liège region offers many outdoor activities. You can find various waterfall hikes, gravel biking routes, and easy hiking trails.

The Montagne Saint-Pierre, located between the Geer and Meuse valleys, is unique due to its limestone subsoil formed over 65 million years ago. This geological history has led to the creation of extensive underground quarries, which now serve as vital bat habitats. The region's calcareous grasslands also support rare plant and animal species, including orchids and various insects, many of Mediterranean origin.
