Hampstead heath, being further out of central London, is probably the nicest suburb park in London. This huge park is extremely scenic, which I think makes it a romantic spot to go to and unsurprisingly, has made its way into a number of rom com films! It's a fantastic place to go to on a hot summer's day, and you'll often find dog walkers, runners, people just out for a nice long walk and lots of couples having picnics and relaxing. It's quite hilly which is good if you want some exercise!
