Biotopweiher alte Tongrube is a small inland pond near Göcklingen in Landkreis Südliche Weinstraße, Rhineland-Palatinate. The water is still pond water with natural banks, without monitored bathing-water data. The surrounding surface is grass, earth, and bank vegetation, mostly open with direct sun exposure and only limited shade. Plan for simple conditions: no toilets, no showers, no shelters, no food or drink outlets, and no lifeguard service. The practical season is June to August, during daylight hours in warm weather. Short stays of a few hours for swimming and sunbathing are most practical. Access involves local paths and a final approach on foot over natural, uneven ground. There is no adapted access for limited mobility. No designated parking is confirmed, so visitors using a car need to use nearby public roads only where permitted and avoid blocking paths or field access. No direct public transport is confirmed, with regional services serving nearby villages, so check local connections before travelling. There is no indication of an admission fee, so expect free access. Bring drinking water, food, sun protection, sturdy footwear, and a bag for rubbish. Because the banks are open with limited privacy and no supervision, choose a discreet spot, keep noise low, and supervise children closely. Unsupervised natural water may not suit young children. Check the water edge carefully before entering and avoid use in poor weather or low light. Since no facilities are indicated, arrive prepared to carry everything out and leave the banks unchanged. Allow extra time for the walk in, keep to passable ground, and plan to leave before light fades.
