If you're looking for some tricks, check out the kids skating under the Queen Elizabeth Hall, right next to the Southbank Centre. You can hear them rolling, jumping and smashing their boards from far away when approaching this spot walking by the Thames (great views!).
Relax on the railing and watch these young guys doing some kick-flips right in front of you. If you're lucky, some graffiti street artists might be spraying the skate park too.
If you're thirsty, you can also have a drink on the roof garden. Look up and follow the yellow concrete stairs!
