If you’re just popping in for a day of sightseeing and overpriced coffee, a day Travelcard is your best bet. For Zones 1-2, it’s about £15.20 – which is roughly the same as a cinema ticket, but you get to watch actual Londoners running for the train instead of a movie. I once bought a day Travelcard and rode the entire Circle Line just to see if I could. Spoiler: I couldn’t, but I did find a great kebab shop near Tower Hill.
Peak vs. Off-Peak: The “I’m Not A Morning Person” Discount
Here’s a secret the tube map won’t tell you: buy an off-peak Travelcard after 9:30am on weekdays, and you’ll save about £5. That’s enough for a pretzel at Camden Market. Off-peak is perfect for people who hate crowds, or anyone who’s ever been squished between a backpack and a stranger’s armpit at 8am. If you have to travel during peak, you’re basically paying extra for the privilege of hearing “Mind the gap” on repeat.
