Hi, I'm almost sure I going to Freekuency Friday morning with my kid that is 3,5 years old.
There is a place for babies and kids and free camping. It's confirmed that it is between Fronteira(1.5 Kms after) and Cabeço de Vide.
The weather seems to be with us.:)
I'll give you my contact on discord when I see you around.
Have a pleasant stay and show-up.
