As a wedding photographer https://www.danielatanzi.com on Lake Como (and beyond) I only usually photograph romantic wedding proposals and engagements. In Como there are many locations where you can make your wedding or engagement proposal.
The locations on Lake Como are paid or free (such as some parks but you have to be careful because there are always many tourists). I also recommend a nice boat ride to view the beauties of Lake Como from the lake for a romantic and special day.
For your love elopements, proposals and engagements, for service weddings /proposal Photos you can write to danielatanzi72@gmail.com
