On July 28 two cavers from the caving club Aenigma: Laura Tamoševičė and Irena Gudaitienė, are leaving for international caving camp in the mountain range of Tendeñera (Huesca, north of Spain). The objective of the camp is to explore the cave system Arañonera (-1,349m deep and 43,700m long). We expect that quite a number of cavers from different European countries will take take part in this camp (last year there was 41 caver from 6 different countries).
