Great advice! I’ve taken both routes mentioned, and I’d just add that the Piccadilly Line is indeed the most direct, but it can get pretty packed, especially during rush hour. If you’re traveling at peak times, you might want to avoid it if you’re not keen on standing.
Alternatively, I’ve found that the Circle Line and District Line route, though it involves a change, is often less crowded. Plus, Paddington Station is quite a nice place to switch trains, and it’s a bit of a break from the hustle of King’s Cross.
Also, if you’re in the mood for a bit of sightseeing, taking the bus can actually be quite pleasant, especially if you catch a double-decker with a seat on the upper deck. It’s a slower journey, but you get to see more of London!
Just a thought: if you’re using an Oyster card or contactless payment, all these options will give you a consistent fare, so you won’t need to worry about paying extra for changing lines or buses.
Hope this helps too!
