"In the local parlance, the parcel of land with the three tunnel entrances in the so-called Kupferberg has always been referred to as the "Goldloch." However, neither gold nor other precious metals have brought any monetary benefit to the island's citizens in recent times. Rather, after mining ceased in the 1930s, the tunnels served as a refuge from bombing raids during World War II and, for a long time, as a secret adventure playground for children. In the summer of 2015, the local community cleared the area. The entrances were then professionally sealed and secured. The forecourt has been converted into an information center about the mines, including a miner's hut, which also serves as a shelter for hikers and cyclists. The open spaces inside the hut are equipped with information panels on geology and the importance of mining for the Eifel region, vividly conveying the history."

The islanders have always called the parcel of land with the three tunnel entrances on the Kupferberg the "Goldloch" (Gold Hole) – even though no gold was ever found there. After mining ceased in the 1930s, the tunnels were used as shelters during World War II and later became a secret adventure playground for children. In 2015, the municipality cleared the area, secured the entrances, and built a miner's hut. Today, there is information about geology and mining history there – and hikers and cyclists can use the hut as a shelter.

A short distance behind the town of Liers (if you walk against the direction of the Ahr river) we come across a small grotto carved into the rock. It houses a statue of the Mother of God, MARY. Below, next to the hiking or cycling path, there is a small opportunity to light a candle for her.

A plot of land with three tunnel entrances in the so-called Kupferberg in Insul has long been known as the Goldloch. Mining there was abandoned in the 1930s. During World War II, the tunnels served as places of refuge from bombing raids. For Insul children, the Goldloch was an adventure playground for a long time.

The impressive structure of this open-air Stations of the Cross, beautifully embedded in nature a little above the village of Adenau, has two grottos: + At the beginning one with a depiction of Jesus' prayer on the Mount of Olives, + At the end one with a depiction of the burial of Jesus. In between, the well-known 14 Stations of the Cross are lined up along the Stations of the Cross.

<< Adenauer Way of the Cross >> "The neo-Gothic Way of the Cross is within walking distance of the market square in Adenau and can be described as a unique cultural monument due to its location and its charming composition of various stone materials from the Upper Eifel. The length of the stations is approx. 700 m with a difference in altitude of approx. 75 m. The historic Way of the Cross is also a small section of the EIFELLEITER premium hiking trail." https://www.eifel.info/a-adenauer-kreuzweg

The impressive structure of the Burial Grotto on the Adenau Way of the Cross, beautifully embedded in nature, is also highly regarded.
While many caves in the region are openly accessible, some, like the Birresborn Ice Caves, have specific access rules due to their role as bat winter quarters, leading to temporary closures. For guided tours, such as those offered at the Birresborn Ice Caves, it's advisable to check in advance for booking requirements or any necessary permits.
The best time to visit depends on the specific cave. Many natural caves and historical mining sites are accessible year-round.
