What is it? Just £30 for two people to fly down the world’s largest and fastest city-centre zip-wire. WHY BUY? The world’s longest and fastest city-centre zip-line is returning to the capital – and you’d be a fool for letting this one pass by. Based in Archbishop’s Park near Waterloo, Zip Now London is the ultimate hair-raiser. From its 35-metre-high tower, you can take in the sweeping views of the London Eye, the Houses of Parliament and Westminster Abbey – as you reach speeds of up to 30 miles per hour whizzing down its 225-metre length.
