St Pancras International and London Waterloo are major termini just 1.5 miles (2.4 km) apart, but no single Underground line connects them directly. The journey requires one change or a surface option.
Alternative: Piccadilly Line to Leicester Square, change to Northern (Charing Cross branch) — similar time.
Exit St Pancras onto Euston Road → west along Euston Road → south up Southampton Row / Kingsway → cross Strand → Waterloo Bridge → Waterloo Station. Pleasant in good weather; passes British Museum, Covent Garden, Somerset House.
Direct from Euston Road/Upper Woburn Place to Waterloo. 15–25 minutes traffic-dependent. Use contactless/Oyster.
Black cab or Uber/Bolt. Fastest off-peak; unpredictable in rush hour.
Step-free: St Pancras → King's Cross St. Pancras (lifts) → Northern Line to Waterloo (lifts at both). Total step-free time ~30 min.
If arriving on Eurostar at St Pancras and connecting to Southwest Trains at Waterloo, allow 45 minutes minimum (30 min if no luggage, familiar with stations).
