There’s nothing more relaxing than spending a few hours in a serene garden taking in the sights, sounds, and smells of nature. This is especially true if you’re visiting a large and busy city like London.  A visit to a garden can allow you to forget for a time that there are millions of people outside its boundaries and can provide a welcome respite from the hustle and bustle of city life.  BLOUIN ARTINFO has compiled a list of the Best Secret Gardens in London.  Maybe you’ll want to look one up next time you visit the “The City.”
