I was here two years ago. It’s about 5 km from my QTH, a nice walk alongside the river Labe. WWFF rules are not good, if you activate the area once, you won’t get any extra points when you revisit it in the future. SOTA rules were better, GMA rules are probably the best.
My equipment was KX2, 10W, and EndFed antenna on a tree. I ended the activation with 47 QSO and had to go to SSB to make enough QSO.
