Even in the London Suburbs you can go chill in the woods. Which is a nice calming thing to do, be it any time of the year. A lot of people may know of Highgate woods,but unless your local you may not know of Coldfall woods.
Once upon a time part of a bigger woodland that included Highgate & Queens wood, this little patch of woodland is an oasis from street traffic, & at this time of year as the leaves are beginning to turn a beautiful spot to walk.
