London's grandest hilltop view, where you can stand on the line that splits the world's two halves.
Tip Climb to the Observatory for the postcard view down to Canary Wharf, then straddle the Prime Meridian line with one foot in each hemisphere. Bring a picnic and spread out on the grass below the hill where locals actually sit. Come back down via the foot tunnel under the Thames for a quirky finish.
