You will get on the peak which is not really peak - you will see when you get there. It is a local maximum and the hill is still elevating from that place.
The peak Mitu?� (859 m.n.m.) is southeastern from rivers Skalka and Moravka junction. It is highly wooded and there is no official tourist route leading to the top, only around the mountain. But do not worry, there is a pleasant track leading to the cache (see openstreetmap) ;)

You can go from both sides. From �spolka follow the red tourist route and then you have to take sharp left and then sharp right right up the hill (see OSM). Or you can go via nad My�ac�m crossroad. The cache is located near peak's official coordinates, northeast from the track.
You can also use a bike to get there, but the downhill trial to �spolka is pretty risky.

In the cache there are magnetics balls that serve just for amusement - please do not take them with you.
