Hi,
If you visit Milano, there is this wonderful nudist beach at river Adda, 30min by car.
You can leave the car at Porto d'Adda cemetery (
) and follow for "santuario s. Maria della Rocchetta", 10mins by walking. Arrived in front of the sanctuary, with a long flight of steps in front of you, turn left following the channel, after the "bar Stallazzo", 5mins walking and turn right straight in the wood, there is a little path descending to the river.
Here the directions (in italian and in english)
https://orsiitaliani.com/adda.htmlThe beach is available from May to September but better checking in advance the flow of the river (pm me and I can check for you on a special website). Most of the people are single guys, some women, some families.
