Unable to answer "What kind of parking is this?" – Parking Lot – osm.org/node/12192554075 via StreetComplete 61.1:

There is no parking space. I'm not sure what this parking space should be. If it is meant to be the parking spaces at the "old anchor" on the left side end of the road, then it has to be moved a lot south, to almost the end of the southern road. If it is meant to be something from the campground, I would remove it.

Large gravel parking lot, also suitable for motorhomes.

Unable to answer "Is the water potable here?" – Spring – osm.org/node/10683433323 via StreetComplete 61.1:

At this place is a hidden beach, I was there all day but I didn't see any kind of water tap etc. (?!)

At this point is a metal gate across the street. When I arrived, it was open. In the evening a man came and said that the road - starting from this gate - belongs to his property (the house at the end of the road).
He wanted me to pay 3€/300 ALL for parking with the car [there was no sign on the gate or whatsoever]. I'm not sure what is the best type to add this information, maybe mark the road as private, or add a "paid parking along the street" etc. After the gate is room for two cars, but there are no official parking lots.

According to Waze, there is a road going down to the city starting at this junction. I didn't go that way, but the beginning is asphalted and looked quite new... Could be important for navigation to add this road. (GMaps doesn't show it)

Steep, small hiking path going down with loose gravel. It ends in stairs which are shown in the picture.

Hier führt ein Waldweg entlang. An dem nördlichen Ende der Aufzeichnung gibt es eine Abzweigung, an der zwei Wege weiter gehen.

Hier befindet sich ein sehr neues überdachtes Parkgelände mit 21 Parkbuchten. Aktuell ist die Nutzung (noch?) kostenlos. Das ist wahrscheinlich nicht relevant, aber das Dach wird gebildet von einer großen PV-Anlage.
