I went for a swim in the Lake D'Orta during our stay here. It was very short and I didn't stray too far from the shore, nor too far from where I started.
The water was clear, fresh, cool (but not cold). It was a real treat!
If I lived on a lake like this, I would probably never swim in a pool. My navigation in open water swims would improve out of sight and I wouldn't run into support craft like I did at Roth the other day.
I would probably have to get a buoy for visibility like this swimmer, who went past while we were eating lunch.
A small sacrifice to make I reckon!
