Travelling with kids on London underground

[TigerBreadAddict]

Hi mumsnetters.
I'm visiting London for a day trip with 11yo and 8yo.
We want to get a single tube from railway station to museum, then back later.
Whenever I've been alone I've just paid contactless. How does it work with kids? We've no oysters etc
Thanks x

Paying for them at barrier, I mean

just go through the wide luggage barriers or see the attendant. 11 is still free I think.

tfl.gov.uk/fares-and-payments/travel-for-under-18s/travelling-with-children Just head for the manned gate to go through.

They're free! Just go through the luggage and pushchair gate.
Have fun!

Thanks: manned barrier it is!
