I'm driving down to tolpuddle for a camping week-end. I should be leaving 10 - 12ish. The route planners suggest going south to get on m25 or going to hammersmith and getting on m3 or going through clapham and twickenham to m3.
Does anyone have any clues what might be the best?
I think OP was concerned about the first part of journey through London, but she didn't say where she was starting from. I would suggest she just makes her way to the nearest M25 junction and go round from there.
From SE London I go on south circ - clapham, wandsworth, A3 down to Wisley get on the M25 to where it joins the M3 (I think its at Junction 1, Sunbury, or mebbe junction 2 - anyway its only about 10 to 15 minutes on the M25, all being well).
I do this journey on to the M3 from East Dulwich very frequently and trust me this is the quickest way. Do not go through London out to M4 and on to M3 that way.
If M25 jammed stay on A3. At some point it joins on to M3 iirc. Sorry, not got map in front of me!
Wandsworth always busy. Especially Saturday mornings. But you will get through it. As soon as you go up the hill after Wandsworth shopping centre, the traffic thins out and you get moving pretty quickly.
