From Victoria Station it is a 15 minute walk..
The whole journey should take about an hour. But if you are there now, there are engineering works that could set you back 45 minutes. Is this a current or future trip?
3Sept, so it would be on the weekend. Will most likely go in on Saturday as well to visit other sites. Hopefully the engineering work will be done by then. Is Clapham Junction easy to navigate?
I see no engineering works for September, but do check closer to the date.
> Is Clapham Junction easy to navigate?
Yes, it is a busy large station but easy to navigate. Use the footbridge to cross to platforms 12 or 14 for a train to Victoria, they are frequent (every 5 minutes or so) and displays on the footbridge show the next train. For your return journey trains to Windsor & Eton Riverside depart from platforms 5 or 6 (both sides of the same island).
Great thanks for the tip
Sounds good, thanks for the info it's very helpful.
