The best way to find is is as was explained earlier. On the way from Amuka to Tzefas, where there is a billboard with a pic of a cigarrette saying "one cig can burn down a whole forest' or something like that, turn left. Drive a min or two and you come to a T intersection. Turn left and you have arrived. I can't seem to find it on google maps now even though they have street view.
Anyone wanna post a G. Maps link?
