All around the Surrey Hills, amazing selection of driving roads.
I work in Croydon and live in the Surrey Hills only takes me 40mins to get home.
If you go to Forest Green, Ewhurst, Holmbury St Mary, Shere and many other villages around there, I'm sure you won't be disappointed!
My personal favourite is the Ockley Road going into Forest Green, also up towards Leith Hill.
I do stress though weekends cyclists love all the roads and week days you come across horse riders especially in Forest Green, so my advice is either go at night or sight the road first.
