What day of they week? There's a fairly large car park at North Greenwich tube station, but it (like most such car parks) gets full by early in rush hour on week days.
Most parts of Surrey have a good rail service into London, so it might be as easy to just get to the nearest station.
Many of the commuter stations in Surrey have car parks which will be pretty empty at weekends.
Sorry - just seen that you said Saturday. If you really do mean south-*east*, North Greenwich car park should have plenty of space, but do check that teh Jubilee line is running from North Greenwich to central London that weekend.
I suspect, tthough, that it's south-*west* you want, in which case a Surrey railway station seems liek the best idea.
As the responses above - do you really mean East, or Surrey which is south or SW of London depending which part?
Most smaller stations in Surrey have reduced parking at weekends, but avoid the bigger centres like Woking with a nearby town centre as they can fill up with shoppers.
Sorry.when thinking of London put East and you are right on I mean West side...Thanks for info
Thanks. Its Guilford where will be that evening so makes sense to go from there into London proper....
However I'm not sure what parking in Guildford is like on a Saturday morning. Hopefully one of the several regulars who live in that part of the world will spot this and comment.
Guildford is a busy shopping town so parking on a Saturday is the same price as any other day. The best car park for the station is this one at £6.40 a day:
But there are fast trains to London every 15 minutes.
Woking has an even better train service and I think the long term car park is £3.
