Ideal location for central London, around 40 minutes on the train which is a 10-15 min walk from the site either through Crystal Palace park or round the road (mind the steep hill on the way back though)! We didn't get the bus but were told it would take about an hour so there's nothing in it transport wise. The bus runs all night, not sure about the trains but we got one back from London Bridge at 11.30ish so will cover a show in the west end. The daily travel pass is £12 for adults and can be used on all buses, tube and overground trains right out to zone 6 so great value for money. The site itself is sloping but with level tiered pitches on gravel. There is a fair amount of road noise but this is to be expected. The showers were lovely, warm and powerful and the toilets impeccably clean. However, beware if you arrive after hours you can't use the facilities as you need a key to access the block. The wardens were very helpful and friendly and we will return to this site on our next trip to London.
