This is a gorgeous day trek through all the local green spaces. Stop off at The Fox for lunch, and finish on farthing down with beautiful views across London.
There's something lovely to see in all weathers, but May and June offer wildflowers galore, particularly on Whyteleafe Bank and Happy Valley.
This walk officially starts at Hamsey Green, but can easily be picked up at Whyteleafe. It ends in Coulsdon, where you can jump on the 434 to get back, or get a train, changing at Purley.
Length: ~10km
