The place I stayed for one night was not suitable for swimming due to an oil layer on the shore. Additionally, there was a constant unpleasant musty smell coming from the lake. Due to these factors, I decided to leave the next morning. However, without the smell, one could stay comfortably for a few days.
The place seems to be a small local wild camping site. There are tents, caravans, and motorhomes everywhere. There are a few spots right by the water. The access is through a longer sandy path with some significant potholes. It is possible but not easy. If you manage to get one of the spots, you will be rewarded with a larger beautiful lake.
There was a lot of activity here over the weekend, with many people camping. There were also a lot of young people who were quite loud, playing music and having parties.
