Imagine your children's face if you come home and tell them that you are going to spend the holidays in one place where they can sleep inside a 'teepee', Isn't it exciting? Well, know that it is possible in Campo Pedralba (Valencia), in a field (not camping) where peace, tranquility and nature reign.
So much is the presence of the latter, that to bathe you can choose between the pool and the river Turia, which passes through there. But although the main attraction is the 'tipis', families will enjoy the silence, the absence of haste, the surroundings, and the proximity of important tourist destinations, at a reasonable distance. 
It is the case of Valencia itself, or Requena (and in the snow season, Valdelinares and Javalambre), but I would not go to Campo Pedralba to move to other places, because workshops are organized there and the surroundings are perfect for hiking or cycling routes.
The countryside is located two and a half kilometers from the picturesque town of Pedralba, perfect to get into authentic rural Spain. Being in the low plains, surrounded by orange groves and vineyards, this area is characterized by a Mediterranean climate, ideal for all seasons
Here you can find more information about accommodation: tipis, 'yurt' (typical Mongolian accommodation) and wooden cabins, and in this link are the prices. A very original idea and full of charm, to spend a few relaxing days, and to let the children run quietly, without fear of traffic.
Doesn't it seduce you?
