Hi back from camping in abbey wood near london and i would reccommend to anyone wanting to sightsee in london.The site is so close to a train station and you could get into london in 35 mins and the trains were around every 20 mins.
The site was a caravan club one and the toilets and showers were spotless. The site was very quiet even though there were a lot of people camping and in caravans.
There was a small play area for kids but not much else really for kids but on the whole if you want to see the sights on the cheap then i would reccommend
