To find the cache itself no climbing equipment is necessary, but little scrambling over rocks will be required. Coordinates are taken in front of the crack that divides Isatis and Gentiane climbing sectors, 5-6 meters from actual cache location. You should go inside that crack and find your way ower the boulder that is stuck inside this crack. Right there in deepest part of the crack you will find cache container.
Small note on cache maintenance: I am here several times a year, fellow geocacher daemondawn visits every six to eight weeks and will help if needed.
