Djurs Sommerland, Construction Site?!

[Gerstlauer1]

On my last visit i came across what may look like a construction site.

Now i'm not an expert on this, so i thought if some of you maybe could help finding out what this is.

 

I took these pics from Piraten's lifthill:

Looks like a couple of piles of dirt.

maybe some piles of new gravel for the parks walkways.....they have similar next to the parking lot at Sommerland Syd.
