Fine, I’ll give you a mini route. Start at Regent Street (the angels). Walk down to Oxford Circus (the glittery stars). Turn onto Oxford Street (the massive snowflakes). Then pop into Carnaby Street (the weird themes). End at Covent Garden for the tree and a hot chocolate. You’re welcome.
One last thing: traffic is a nightmare
Don’t drive into central London during these switch-on days. Seriously, you’ll be stuck. Just take the Tube. And wear comfortable shoes. You’ll walk—a lot. And probably spill mulled wine on someone. It’s tradition.
So, when is the London Christmas light switch on? The short answer: be ready by early November. The long answer: just Google it in September. And the fun answer: whenever you decide to show up, because they’re always on somewhere. Now go forth and get festive, you glorious winter-loving fool.
