Go scuba diving in the crystal clear and scarily deep waters of Zakrzówek quarry. Advanced and beginner diving courses are available (in spring and summer only) for those who can somehow get around the fact that the instructors don't speak English. The depth varies from 7-21m (23-69ft) and the bottom is cluttered with all kinds of things that shouldn’t be there: several vehicles and sunken boats, including a small aircraft with two fake skeletons in the cockpit, as well as the former changing rooms of the quarry workers.
