Reaching The O2 arena from London Victoria is straightforward on the Underground. Begin by taking the District or Circle line eastbound from Victoria station—just one stop—to Embankment. At Embankment, follow signs for the Jubilee line and board a northbound train toward Stratford.
Remain on the Jubilee line for 13 stops until you arrive at North Greenwich station. The journey from Embankment takes roughly 20 minutes. Upon exiting North Greenwich, you will find yourself directly in front of The O2's main entrance, with clear signage guiding you to the venue.
