I want to mention this place, which many people may not be aware of, I think. It is my duty to mention this here so that more people can have some fun.
It is somewhat busy depending on the time, but you will always find one or two people. People park up at the spot, looking for fun.
The place is called Wort's Causeway. Typing the name into Google search and adding words such as 'gay cruising spot' or 'Cambridge' will lead you to instructions on many sites, which explain better than I can. But I will put a link below that explains how this spot works and how to get there
