This is the start of the walk up Box Hill, a scenic National Trust spot in Surrey overlooking the Downs.
Box Hill is a well known beauty spot in the North Downs of Surrey, England, close to the southern outskirts of London, overlooking Dorking to the south-west. There is a small village of the same name about 1.5 kilometres (0.93 mi) to the east. The hill is named after the box trees which can be found on its steep southern and western flanks, notably around the "Whites", chalk cliffs cut by the River Mole - which you can see in the picture.
This stepping stone is a very busy place and in summer it's almost impossible to find a quiet moment in which to take a photo! The funniest thing is when walkers with dogs cross the stones - half the dogs run up to the stones, brake suddenly and then give an incredibly quizzical 'and what am I supposed to do now' look, whilst the other half just leap in the water. Great fun =)
Update 2012: You may come across the name "Box Hill" during the London Olympics, specifically the cycle race. The route forces olympians to cycle up and down this whole hill 7 times, which I tell you, rather than them me. This scene is literally at the bottom of the hill that you'll be looking at on TV! So come and visit Box Hill before or afterwards, and enjoy a beautiful walk up the slopes of the hill. And if anyone has spare tickets, pop me a mail! Thanks!
