No special access issues
On the other side of the swamp-lake there is a summer cottage. When the residents are there, make sure to mind them and keep your volume low. Metsäkoivula's hiking trail passes the cliff, so there's a lot of non-climbing foot-traffic. Be sure to to be kind to passing strangers. And keep the cliff clean! Every single piece of trash must be collected.
The parking area for the cliff is located at the beginning of the said trail, with space for around 8 cars. Park in a way that allows for others to move. At the parking spot, there is sufficient area for tents. The address for the parking area is:
Levolantie 67, 31400 Somero
Accessing the crag is by using the same hiking trail. The trail is well marked with blue paint. Turn left when the red route ("Hirvenpolku") starts and walk down the slope until you reach sector #1. The approach takes 20-25 minutes, the length of the approach is 1.4 km.
