Then it's time to check the coordinates, look for hidden clues, solve the riddles and, once everything is right, dig up the treasure. Geocaching is not just a challenge for the brain and technology, but is also an intensive and sensory nature experience. We navigate you to special natural phenomena, places and views in the Eifel National Park and its surroundings. Digging up the treasure often starts a new story. Use the stethoscope you have found as the "tree treasure" to listen to the trees' voices or a piece of coal could lead you to a time with smoking piles. A playful familiarisation with the National Park region, time to enjoy the beauty and a varied fringe programme - a nature experience par excellence for adults and children alike!
