No special access issues
Climbing is allowed, but with caution due to the following factors:
From what I understand, there has been a life lost here. On the base of the quarry, there is a shrine with candles. If you decide to climb here, be extremely respectful, maybe even bring a candle or flowers of your own to honor the memory.
The other important thing to be aware of, is that the surrounding area is a nature reserve since 2016. It is a protected hazel and black alder grove. Siberian flying squirrels have also been seen in the area. Even though the climbing area itself falls short of the nature reserve's reach, be sure to respect nature even more than usual while visiting.
