Up at the O2 Tickets

"We booked up at the o2 tickets for a 7pm slot in July and the light over the Thames was worth the whole thing. The fabric walkway bounces underfoot more than I expected, which sounds unnerving but turns out to be half the fun. From the summit platform you can pick out Canary Wharf, the Greenwich Peninsula bend and the cable car crossing below."

"El ascenso a la cúpula del O2 fue lo mejor de nuestro viaje a Londres. The climb suit and harness make you feel properly kitted out, and our guide kept the small group moving without rushing anyone. Halfway up the incline the whole Docklands skyline just opens out in front of you."

"From the ground the Millennium Dome roof looks like a gentle slope; on the walkway it is steeper and springier than photographs suggest. We had a light drizzle at the start and it cleared by the summit, so the Thames looked like sheet metal under grey cloud. Our group of ten stayed together the whole way and nobody struggled."

"We took our up at the o2 tickets tour on a blustery April afternoon and the gusts at the top were strong enough that we held the rail with both hands. The guide explained the mast structure and how the Teflon-coated fabric is tensioned, which I found more interesting than expected. Only note: the descent is quicker than the climb, so savour the platform time."

"Living in London I had walked past this thing for years without going up. The O2 roof climb gave me a view of the river bend I have never had from anywhere else, with the sun setting behind the City towers. Small group, calm pace, and the harness system means you are attached the entire time."

"We used our up at the o2 tickets tickets on a cold February morning and the low sun made everything sharp and clear across to the Isle of Dogs. Bring gloves — the guide rail is cold metal and the wind off the Thames finds every gap in your jacket. The climbing suit goes over your own clothes, so layer up underneath."

"Nous avons réservé la montée sur le dôme de l'O2 pour un début de soirée et la lumière dorée sur Canary Wharf valait le détour. The walkway surface has a slight give to it that takes a few steps to get used to. At the summit our guide pointed out the Greenwich Observatory and the Thames Barrier in the distance."

"We climbed on a bright autumn afternoon with barely a cloud, and from the platform you could see well past the Docklands towers. Among London landmarks this one gives you an angle nobody else has — looking down on the arena roof rather than up at it. The safety briefing at the base station was thorough without being tedious."

"Our up at the o2 tickets tours slot was after sunset and the whole peninsula was lit up, cable car cabins drifting across the river like slow lanterns. The incline felt harder than the descent and my legs noticed the next day. Solid handrail the whole way, so no real balance worries."

"Wspinaczka na dach O2 była świetnym pomysłem. The fabric roof panels look enormous once you are standing on them, and the yellow masts are far taller from up close than they seem from the car park. Our guide timed the summit stop so we caught the last of the afternoon light over the river."
