Is it possible to reserve a campsite or is it first come first serve ?

It's not possible to reserve, because owner has no internet, computer etc 😀, but don't worry there is enough parking spaces. It's FCFS... Enjoy...

I have not been there that time of year, but I would imagine they are pretty busy then.

Thanks Boris ! Last question : we will not arrive before 5 or 6pm. We will be there on the 6th of may do you think it will be ok regarding camp Space ? Thanks !
