Located just six kilometers from Trafalgar square and easily accessible on the London Tube, Hampstead Heath provides a green respite and a place to play and relax not just for Londoners, but for one and all. This unique ‘green lung' of the city was actually a remnant of the great Middlesex Wood. It has surprisingly retained its rustic charm as the metropolis flourished around it. The appeal of Hampstead Heath also lies in its abundant wildlife, with a few priority species identified in the UK Biodiversity Action Plan. So if you are looking for some fresh air or a haven to sweat it out, do consider exploring one of their many wonderful trails.
