Hi there, i have just been told of a hide for photography at el Planeron zaragoza, that has a constant stream of water fed to it that attracts pin tailed and black bellied sandgrouse to drink, also used by all the larks. This is meant to be a 3 person hide at ground level which is close to the water. Is this hide accessible to just turn up and use or do i have to book to use it? Where abouts on the reserve is it situated as ive been 3 times before and never seen it. Any information is greatly appreciated.
