Behind Markfield Beam Engine is the River Lee which travels from the Chiltern Hills all the way to the Thames via Tottenham Hale. There is a special light along this stretch of the river possibly due to there being about 10 massive reservoirs behind the levee on the other side of the river, offering an amazing sense of space. A great place to walk, cycle and feed the ducks, swans, geese and coots.

This may not be much of a secret but deserves a mention. I find it hard to go anywhere near this place without having to go there. Freshly baked Beigels hot salt beef and it never closes, 24 hours a day 7 days a week.

Lovely, open space close to Highbury and Islington with tennis courts, netball courts, kids' playground and Parkrun on a Saturday morning at 9am!  

Excellent Turkish bakery. I highly recommend their £2 gözleme.

There are not many places in London like it. On a Saturday during market hours it heaves with stalls and visitors for a good mile or two. Great place to pick up some bric-a-brac, genuine oddities and a great bite to eat, or just enjoy the hustle and bustle vibe of the place.
