The Surrey Hills area is a mecca for mountain bikers, with rich terrain offering something for riders of all abilities. I’ve been riding here on and off for about 5 years now, following a route originally downloaded from a site that’s long since disappeared. It’s a pretty tough tour taking in four of the highest hills in southern England, but includes a bail-out loop if you want to cut out Peaslake and The Hurtwood.
Many of the areas along this route can give you hours of entertainment in their own right, especially if you discover some of the excellent singletrack that’s been cultivated by various clubs and riding groups. There’s also pubs galore and some neat bike shops to explore, so you’ve really no excuse but to get out there. You can download the track log here.
