Up at the O2

WOW! This is a must if you aren’t scared of heights! A great experience with the most fantastic views.
I would recommend booking online for sure — the weekends get booked up very quickly and it is also slightly cheaper.
My friend and I however didn’t realise because it looked available online that those were only for 1 space (it is actually quite clear if you read it properly!) so rocked up about 5pm hoping to go on the 5.30pm. We basically had to wait for someone not to show up and got lucky about 7pm.
It worked fine for us as we sat around playing cards and chatting on a sunny evening. We went up and reached the top as the sun was going down behind some clouds which gave the sky a beautiful orange colour on one side overlooking canary wharf and a lovely blue the other direction. We were really lucky with the weather as it had rained the day before which is why we weren’t too keen on booking.
The walk is actually quite steep however fairly slow going so not too strenuous. You have a good amount of time at the very top to take pictures and soak in the views. You are allowed to take phones however not big cameras — which is a shame but you can see why on the walk up!
A definite recommend.

If you like a good view and are not put off by a bit of height (52m) with a steep ascent/​descent (25−30° at steepest) then this is a fun event with a 360° view.
Group and private climbs can be arranged.
Safety is one of the main concerns with a harness attached safely to a line on the way up/​down and a wire hand rail to assist. Photos are taken which you can buy at the end from the shop.
All in all a good experience.
