The Mullerthal trail is a hiking trail in eastern Luxembourg, which includes several waterfalls along its route. One of the most popular waterfalls on the trail is the Schiessentümpel waterfall, which is located in the Mullerthal region's Black Ernz River valley.

The Schiessentümpel waterfall is formed by the Black Ernz River flowing through a narrow gap in the rock, creating a series of cascades and pools. The area around the waterfall is wooded, with moss-covered rocks and boulders, giving it a magical and mystical atmosphere.

The waterfall can be reached via a hiking trail from the nearby village of Mullerthal, and there are several other waterfalls and points of interest along the way. The entire Mullerthal trail is 112 kilometers long and is divided into three sections, each with its own distinctive scenery and attractions.

The Mullerthal region is also known as "Little Switzerland" because of its stunning landscapes, rolling hills, and dense forests. The area is a popular destination for hikers, nature lovers, and outdoor enthusiasts who come to explore its picturesque villages, historical landmarks, and natural wonders.
