How much is thet ube fare from kings cross to Victoria?

As of my last knowledge update in September 2021, the standard (off-peak) fare for a London Underground journey between King's Cross St. Pancras and Victoria station is £5.30.

Please note that fares may have changed since then due to regular updates and revisions in travel tariffs. For the most current and accurate information about transport fares, including any potential discounts or special offers, it's always best to consult the official TfL (Transport for London) website or mobile app. Real-time travel information provided by TfL will ensure you have the most up-to-date details regarding fares, routes, and any temporary disruptions on the London Underground network.
