This is the smaller, more accessible lake that emerged after the basalt quarries near Forst were abandoned in the 1980s. Today it's a nature reserve, so you'd better avoid swimming here. It's definitely worth seeing.

Here stands Ritterstein No. 260. It is one of over 300 Rittersteine (memorial stones) erected by the Palatinate Forest Association (PWV) and bears the inscription "Heidenlöcher – Refuge Castle 9th-10th Century." It marks the remains of a refuge castle that served as protection against the warring Normans and Hungarians. Today, the foundations of two gate structures, 65 stone houses, and a 450-meter-long curtain wall are still preserved. The inner of the two adjoining dry-stone walls served as a parapet walk. - Source: Information panels on site A little further to the right of this Ritterstein are the foundations of one of the gate structures. The refuge castle, or rather its remains, can be entered through the two gate structures. The curtain wall can be easily walked along (with minor exceptions): either on top of the wall or along its inner side – and the remains of many stone houses can be seen along the way. Without Komoot, it is easy to get lost here: Therefore, it is best to follow the "Palatinate Wine Trail" hiking signs!

In contrast to the (red) quarries in the middle of the Palatinate Forest, sandstone on the Haardt edge is white and yellow! Many of the inscriptions/pictures that can be found on the walls are explained on a beautiful information board and marked with red arrows on the walls of the quarry. Horse pictures are particularly easy to recognize. These rock paintings come from the Roman legionnaires who worked in the quarry here. Also carved into the stone: a large memorial plaque for the Bad Dürkheim soldiers who died in World War I and all their names.

Impressive ruin - due to the well-preserved ruin, it is easy to get an idea of the former monastery.
