On a hot day there is nothing better to do in London then go for a swim in the Heath ponds. You get completely transported you out of the city as Hampstead feels like being in the countryside except you're in central London?!

I rediscovered this place recently having not been for years and now I keep returning. The geological galleries are my favourites.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

Arguably the best café in London – or at least East London – with an incredibly welcoming atmosphere, delicious array of food and drinks, and hypnotising views to Broadway Market. Visit early in the mornings, for a roque-monsieur at lunch, or to get lost in their cheese selection at the market stalls on Saturday. Warning: addiction likely to occur.
