Story of the box: I'm inviting you to a short hiking into the Pilis hills at Klastrompuszta. This multi-cache consists of 2 parts. Both of the two boxes can be found under rocks. The distance between the caches is a few hundred meters only in bee-line. I recommend you to take my pictures with you to help you in your way. You have to turn right and go on the walkway signed with red square toward the so-called Legény-barlang (Legény-cave). After a few meters you will see the so-called Pálosfa and the ruins of the cloister. You still have to follow the red square and after that the red cave sign. The first box is in the entry of the cave under some rocks. You have to find a little box. This box contains the coordinates of the next box (cache). The downhill road rises boldly and it is slippery. When you have found the box and noticed the coordinates go to the cache. You can find any surprise in the 2nd box only. Otherwise, the first box is the most difficult, the second is easier as easy as apple pie. GPS signal is very poor in the forest. Please pay special attention to your children at any points. The last box is a round-box with a diameter of 15 cm and a depth of 13 cm. After having found the last box, please check the overlook, too. It is the so-called Kémény-szikla. This overlook is the attraction of this multi-cache. Good luck!
