To find this cache you need to hike a bit. Therefore, hiking shoes or good trainers with nonslip sole are highly recommended. From the bottom of the hill to the top there is a difference in altitude of around 135 meters. It is no difficult terrain but you should avoid going there if it rains or just has rained. It might be too slippery.
If you decide to park the car at the school you can warm up your muscles on an 800 meter walk past the quarry before you start your ascent. You will see locals working just with hammers to break up the rocks. Once you have passed them this is the best place to start to hike into the direction of the top. This is roughly to the South of the summit at N 2°17.115' E 32°55.972'. The ascent will take around 30 minutes. You will need to go up to the very top to find the cache.
Especially around weekends the place might be a bit busy as local people like to go there for exercise reasons or for picnic. But the actual place of the cache is in an area which is slightly protected against curious eyes of muggles.
