During the post-Symposium excursion typical gravity induced caves in the Beskid Wyspowy Mountain Group (Mt. Łopień), several hundred metres long, will be explored (see PICTURES), therefore typical cave equipment (light, hardhead and coverall, but not rope) and adequate skills are necessary. Shorter but not less interesting non-karst and karst caves will be visited in the Pieniny Mountains (see PICTURES). The access to the visited caves requires walks up and downhill (0.5-2 hour). The excursion will be closed at midday/afternoon, 10th June in Kraków, therefore Kraków is a convenient place of arrival and departure of this excursion participants. We can also help in an arrangement of longer stay in Kraków.
