THIS COMPETITION HAS NOW CLOSED
Up at The O2 has teamed up with Parentdish to give one lucky family the chance to experience something exhilarating.
This is a day out with a difference and the opportunity to climb one of London's most iconic landmarks, The O2, home to the world's most famous arena.
The 90-minute expedition offers an unforgettable challenge to conquer the summit and rewards visitors with spectacular 360 degree panoramic views across the capital.
Dressed in full explorer attire, climbers will conquer the heights and soak up the city, with an experienced guide on hand to talk them through every step across the 350m walkway.
Visitors can enjoy the tremendous sense of achievement when they reach the top of the viewing platform, which sits 52m from ground level.
One lucky winner will receive four tickets to an Up at The O2 session. The tickets can be used at any time, but must be used within 12 months. Children must be aged at least 10 years and be at least 1.2m tall to climb.
For your chance to win, enter your details below before 10am on November 21.
Good luck!
