According to the symbols in the middle it is:
motor_vehicle=no
foot=designated
bicycle=designated
horse=designated

The sign on the left says, if the translation is correct:
The path is privately owned and leads through a nature reserve "XARXA NATURA 2000" https://natura2000.eea.europa.eu/?sitecode=ES5310034&views=Sites_View
and: Do not remove the sown. nor do you go off the beaten track. The cams must always be firmed. It is forbidden to make fires and illuminate manure.

So acces could be private or permissive.

The unreadable sign in the centre could provide further information. possibly the sign on the right too.
