Can anyone recommend a nice camp site in North London for one night – we are going to Alexander Palace if that helps

Hmmm think you might struggle. Nearest one is either Epping or Lee Valley:

Have a look around the Lea Valley & Broxbourne.

Quite a nice cycle down towpaths to Alexander Palace if that helps

Lee Valley Almost Wild Campsite, etc…

How are you getting to Ally Pally? It’s on a train line so you could pick a place further out the train line?

There’s free parking there but traffic can be horrific

We were going to go for public transport as its the red bull soapbox – any suggestions for further out gratefully received

If you are coming on a bike you could try warm showers.

Sorry posted at as I was writing.

haha what?

Tube is open all night, Hampstead Heath can be fun of an eve,

It’s with the family unfortunately, otherwise warm showers is an excellent idea

Hertford & Train then

linky

Cheers, thats where my thoughts are going – stay further out and catch the train in
