I'm going to leave some practical details that are missing from the other reviews, that I wish I had known before hand:

We nearly missed the entrance which lies between some derelict buildings and is marked with just a faded plaque where the name of the park is written with the thinnest font in existence. Thank God for the lovely lady at the Farmoury shop who saw us rambling wide eyed and confused.

There is no signage within the park whatsoever. There's an online map, but paths are not always well defined and landmarks are unknown to us, so you never know where you are or if you are even within the park perimeter anymore.

There are no garbage bins. Not in the park, not at the entrance, not at the visitor center. I found some old broken soda bottles and a shotgun shell and wanted to throw them away, I walked all the way to the visitor center and there was no way to dispose of them. I found a construction container a little further away. If the park can have abandoned buildings and hunter huts marring the natural environment, it can also accommodate a garbage bin or two.

The toilets at the visitor center were closed on a Friday at noon. There are no other toilets in the vicinity.

It was nice to spend some time in nature, the walk was doable and safe for little kids, so it was a very positive experience overall and I recommend it.
