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 that is often tended to. 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.
Public transportation:
There are many busses which lead quite near the crag,
for example:
335 Uudenkyläntie - Linnainen
345 Elielinaukio - Rinnekoti
566 Martinlaakso - Espoon Keskus
583 Aviapolis - Perusmäki
584 Aviapolis - Kalajärvi
All of these have an approach that is under a kilometer to the crag.
Transportation by car:
I have no idea currently where there would be parking. I will be figuring this out and adding it to the information here.
