However, if you are ok with heights and can put up with the stairs, the views from the top are amazing. I'm just a bit annoyed I couldn't get a decent shot of the Shard because of where the sun was. Still, at only £3 (!! View From the Shard is £25!) all this complaining is a bit churlish, so let's get on with the pictures.
In case it isn't obvious, I highly recommend this activity. Preferably with some maltesers ready for when you get back down.
