You can get there by going to Kubekhaza first, then follow the yellow "Triplex" signs on the dirt road for about two kilometres. Don't leave the signs because you might find yourself outside the European Union. The monument is near a huge Serbian watch tower. It was deserted when I was there. The monument has three sides and the three coats of arms with the dates of the creation of the border. The cache is on the side of a small "island" of reeds.
For the past few years, the triple border has regularly been opened for the citizens of the neighbouring countries on the last weekend of May. On an occasion like this when you have left Hungary, you can decide if you want to turn left into Romania or right into Serbia. The people from the neighbouring villages can meet each other. Their grandfathers might have known people from the other villages but now they don't because the border had been closed for about 80 years, which is almost three generations.
The former mayor of Kubekhaza initiated the monument and the opening of the borders at the so called Triplex Confinium (Triple Border). Now the neighbouring counties of the three countries form a European Region. Their homepage is: (visit link) where you can find news and information on the development of this area.
Kubekhaza (founded by an Austrian military officer called Kubeck in the 19th century) is also famous for being the Operetta Village. Every summer they hold an open-air festival with the best operetta singers from Budapest.
Come and listen to the sweet melodies of Strauss, Lehar and other composers.
