England’s longest zipline opened to thrill-seekers at Bluewater today - and the winners of our latest competition could be among the first to try it out.

Hangloose Adventure is 720 metres and will come to the cliffs around the shopping centre for an adrenaline-inducing day out.

Hangloose Bluewater will be the biggest adventure centre in Europe and the zipline is just the first of a number of activities coming to the site over the next two years including Britain’s only outdoor Skydive machine; one of the largest swings in Europe; a bungee jump and a massive climbing wall.

We’re offering the chance for two families of four to try Hangloose for themselves - and have a video of their flights to remember the experience.

To be in with a chance of winning click here to enter by midnight on Sunday, July 4.
