Throughout April and May, the Black Trout Adit in Tarnowskie Góry will be available to individual tourists on Saturdays, Sundays, and on holidays. The longest underground route in Poland that tourists cover with boats will be open from 10.00 to 16.00.
On weekdays, the facility will be available only for organized groups for the next two months, which will be booked earlier in the Tourist Service Office (email@example.com or 32 285 49 96). Hours of sightseeing are determined individually during the phone booking.
There is a possibility of adding individual tourists to organized groups, but after having contact with the Tourist Service Office.
