London sites?

[Millimat]

We are planning on visiting london in Feb half term so can anyone recommend a decent site for our caravan? Not bothered about many facilities, just decent showers and toilets, but with easy access into london?
Thanks

Crystal Palace! No idea what it's like (although the views are fantastic), but it is certainly nearest the centre - it's just in the edge of Zone 3.

Abbey Wood - Zone 4 - five minute walk from station - 25 mins to London by train. Think it's a Caravan Club site - check it out.

Debden House campsite is 5 mins drive from Debden Central Line tube (which is itself about 30 mins into central London) - the field for caravans has electric hook up and a children's play area centrally - it's also the field closest to showers and toilets in the main admin building - we only overnighted so didn't use the showers but on inspection they appeared clean, hot and large enough to take the whole family! The loos were spotless.

The site itself backs onto Epping Forest and you would never know you were so close to London.
