The tunnels are a Crane.tv favourite. We have used the space as a backdrop for several films including a music session with The Civil Wars. The tunnels have a great story behind them and feature one of the only legal graffiti walls in London on their Leake Street side which was championed by Banksy back in 2008.
I love swimming and I love being outside. London is great if your into both these things. I swim at London Fields Lido which is heated all year round. Its best in the winter when the steam rises from the water and if your lucky its snowing a little on your head. If your brave you can also go for the unheated option of the Serpentine or Hampstead Ponds.
South London is largely underrated considering at times it's a treasure chest of gems; Battersea Park is one of those big sparkly ones. An interesting mix of faultlessly pruned gardens, displaced architecture, shape, form and colour generate a delightfully influential weekend stroll. With views of the almighty Battersea Power Station and the river dividing you from the Chelsea Embankment.
Tate Modern can always be relied on for offering up interesting, challenging exhibits, housed in great architecture and with one of Londons best cultural bookstores. An ever reliable weekend hangout.
