Very nice "beach" to come. The Geneva Lake water is so clean and nice and there is also sand . Bathrooms are available, paid ones to the far right and free ones by the kids playground. You can even swim with the swans. Lots of café shops to grab some snacks and drinks, but beware for the swiss cost 😉. There is showers to clean up before you leave. Be sure to bring a sunshade because there a very few spots with shadow.
So glad this beach finally opened. There’s plenty of space to sit, outdoor showers, a water fountain, public bathroom (pretty clean), and a restaurant in the works (it should open April 2021).
