Kohlscheuer is one of the most impressive rock formations in the Luxembourgish Mullerthal region, also known as Little Switzerland. It is characterized by extremely narrow and dark rock crevices, some of which can only be traversed with the aid of a flashlight. The creation of these sandstone formations dates back to erosion processes that have carved deep fissures into the Luxembourg sandstone over millions of years. Hikers particularly value Kohlscheuer for the adventurous nature of the passage, with some sections so narrow that one must move sideways to pass through. The surrounding landscape is dominated by dense beech forests and high humidity, which promotes the growth of rare mosses. Geologically, the area belongs to the layered landscape of the Paris Basin and is a central point of the Mullerthal Trail.

📋 Practical info

🚪

Visiting

The Kohlscheuer crevice is freely accessible to hikers and does not require any ticket. You will need to squeeze through extremely tight rock passages, so be prepared for a physical challenge.

🕒

Typical hours

There are no official opening hours for this natural landmark, so you can visit at any time. However, visitors typically come during daylight hours, and the crevice becomes very dark after sunset.

📷

Photography

Photography is allowed inside the crevice, but the complete darkness makes it challenging. A tripod or flash is recommended to capture the narrow rock textures without motion blur.

⏱️

Time needed

Plan about 15 to 20 minutes to squeeze through the narrowest section of the crevice. Including the approach hike and return, the entire outing typically takes around one hour.

➕

Combine with

Combine your visit with the nearby Schiessentümpel waterfall or the Hohllay cave. The Müllerthal region is full of similar rock formations, and a full-day hiking route connects many highlights.

🧭

Getting there

The easiest access is from the parking lot in Müllerthal village, following the marked hiking trail signs. The path is uneven and rocky, so sturdy hiking shoes and a good level of fitness are recommended.

💡

Insider tip

Bring a headlamp or a powerful flashlight - the crevice is pitch black inside. Visit early in the morning or on a weekday to avoid queues in the extremely narrow sections.
