To get to the location you can either go through rif if you are coming from salzburg and park near the houses next to the cache (It's private property so not recommended) or take a right after the roundabout and go past the sportscentre and the road across the field (Dorrerbauer) This gets you the closest to the cache.
If you are coming from Hallein you can take the same route via Rehhof and the the path across the field. This is the better option because there are far more parkingspots available.
To log the cache a tool is definitely needed. Either buy one or make it yourself from sticks nearby ( Don't break any new branches off trees)
After you found it and have a spare 20 minutes take a walk through the forest (the Au) and do the training course provided by the Sportscentre.
Other than that it's a normal container. Have fun caching and logging.
